Directions: The children can be sitting at their assigned seat or in a circle. Have two students that are next to each other stand up. Then show a number on one of the cards. The student that says the number first moves on to the person next to them. If there is a tie, the two students get another number until there is a winner. Continue until all students get a turn or a set time runs out. Differentiation/Accommodations: You can differentiate the numbers being used based on your students level by using numbers up to 20, 50, or 75. You can also do this in a small group setting to make sure students get multiple turns. Primary Math Intervention Activities Columbus City Schools 2011-2012 Counting On Domain: Counting and Cardinality Cluster Statement: Know Number Names and the Count Sequence Materials: 1-100 Numeral Cards (You can use index cards to make your own.) Directions: Have students sit in a circle (this can be done small or large group). Choose a student to pick a card from the pile of numeral cards. The next student says the next number and so on until the students get to 100. If a student makes an error in counting, have the next student pick another number from the numeral card pile and start again from that number. Differentiation/Accommodations: You can use lower numeral cards for struggling counters and have them count up to a lower number. Another way to play the game is counting backwards from the number on the numeral card that has been picked by the student. The students can count down to 0 before picking a new numeral card. Primary Math Intervention Activities Columbus City Schools 2011-2012 Matching Card Game Domain: Counting and Cardinality Cluster Statement: Know Number Names and the Count Sequence Materials: 2 sets of Number Cards up to 100 A deck of playing cards (2-10 only) Directions: Start by putting out 2 sets of numbers 1-10 (20 cards in all) in 4 rows of 5. Have one student flip over 2 cards to see if they match. If the cards match the student keeps them and goes again. If they do not match flip the cards back over and the next student has a turn. Keep playing until all cards are matched. Use different numbers next time you play depending on your student’s level. Differentiation/Accommodations: Use the deck of playing cards for students that have difficulty. Lay out 2 of each number in 3 rows of 6. Have a student flip over 2 cards and count the symbols on the cards to see if they match. Keep playing with the same directions as above. Primary Math Intervention Activities Columbus City Schools 2011-2012 Popcorn Counting Domain: Counting and Cardinality Cluster Statement: Know the Number Names and the Count Sequence Materials: None Directions: Have a small group of students sit in a circle. A student starts by saying 1, then the next student says 2, then the next student says 3, then the next student says 4, and etc… When a student gets to a decade number (10, 20, 30, 40, etc…) they pop up and say that number. Continue counting until a student makes an error when counting. You can either play again starting at 1 or stop playing the game. Differentiation/Accommodations: If a student makes an error, you can correct it and keep playing the game. For beginning counters, you can give each student a number line or hundreds chart to follow along as students count. Primary Math Intervention Activities Columbus City Schools 2011-2012 Bears in a Jar Domain: Counting and Cardinality Cluster Statement: Count to Tell the Number of Objects Materials: Colored counting bears Jar Directions: Begin with a low number of bears in the jar such as 5. Shake the jar and ask students how many bears there are now? If students need to count the bears, then they do not understand the concept of cardinality. If students respond “5”, then they understand cardinality. Continue to practice with different numbers of bears in the jar. After shaking the jar pour bears out and ask how many. Once students consistently respond with the number without recounting then they have mastered cardinality. Differentiation/Accommodations: You could substitute different manipulatives in the jar such as cubes, counters or dot cubes. Primary Math Intervention Activities Columbus City Schools 2011-2012 Dashing Dots Domain: Counting and Cardinality Cluster Statement: Count to Tell the Number of Objects Materials: Dot plates Directions: Show a dot plate for only a few seconds. Teacher asks “how many?” Students need to name the number of dots within a few seconds. Students should begin to recognize patterns quickly. Differentiation/Accommodations: Teacher can have students name one more or one less than on the dot plate shown. Eventually teacher could have students name two more or two less than on the dot plate shown. Primary Math Intervention Activities Columbus City Schools 2011-2012 Dot Cube Subitizing Domain: Counting and Cardinality Cluster Statement: Count to Tell the Number of Objects Materials: Two dot cubes Paper for recording points Directions: Students take turns rolling the dot cubes. When the dot cubes stop the student calls out the number of dots within a few seconds. If correct, student gets a point. Second student rolls the dot cubes and calls out number of dots. If correct, that student earns a point. If incorrect, student rolls again. If students have to count the number of dots on the dot cubes they have not mastered subitizing. Continue playing and practicing the skill. Student with most points is the winner. Differentiation/Accommodations: This can also be practiced without playing for points just teaching students to recognize dot patterns. Primary Math Intervention Activities Columbus City Schools 2011-2012 Domino Subitize Domain: Counting and Cardinality Cluster Statement: Count to Tell the Number of Objects Materials: Set of Dominoes Directions: Make sure all dominoes are face down on the table. The first student flips over a domino and says the number of dots. If he/she is correct then they keep the domino. The second student flips a domino over and says the number of dots. If correct that student keeps the domino. If student doesn’t name correct number of dots then domino remains face down on table. The student with the most dominos at the end is the winner. Differentiation/Accommodations: Try using double-nine dominoes for a challenge. Primary Math Intervention Activities Columbus City Schools 2011-2012 Number Show and Tell Domain: Counting and Cardinality Cluster Statement: Compare Numbers Materials: 2 Number cubes (labeled 1-10) Index cards Marker 10 frame Counters Popsicle sticks Directions: Three students are needed to play this game. First player rolls the number cube, shows the other players the number, and writes the number on index card. The second player represents the number with popsicle sticks shown as tally marks. The third player represents the number with counters on a ten frame. Players check to make sure all representations are correct. Players can trade and represent numbers in different ways. Play continues until all numbers have been represented. Differentiation/Accommodations: Represent numbers only 1 or 2 ways. For higher levels have students represent 2 digit numbers with beans, sticks or base ten blocks. Primary Math Intervention Activities Columbus City Schools 2011-2012 Number Scale Domain: Counting and Cardinality Cluster Statement: Compare Numbers Materials: Number scale Directions: Pick a student and have them place a blue weight on each side of the scale. Discuss what happens once the scale stops moving. The side of the scale that is up has the smaller number (lesser than) and the side of the scale that is down is the bigger number (greater than). If the scale stays the same that means the two numbers are equal. Differentiation/Accommodations: Have students write out the numbers and symbol for greater than (>), less than (<), or equal to (=) in a math journal or white board. Primary Math Intervention Activities Columbus City Schools 2011-2012 War Domain: Counting and Cardinality Cluster Statement: Compare Numbers Materials: Set of playing cards Directions: Distribute even number of cards to each player. First player flips card over, and then player two flips card over. Whoever has the larger number keeps both cards. If both players flip cards over with the same number, then they each flip another card over. Whoever has the larger card keeps all of the cards. Continue play until all cards are used up. Differentiation/Accommodations: You could modify this by having the lower number win. Primary Math Intervention Activities Columbus City Schools 2011-2012 Nifty Number Lines Domain: Counting and Cardinality Cluster Statement: Compare Numbers Materials: Laminated number line with numbers from 1-10. Two number or dot cubes with numbers 1-10 Directions: Have students roll the number or dot cube. Have them put a finger on the number rolled. Ask them questions about greater or less than. Ask them how they know? For example 7 is less than ten because it comes before ten on the number line. It’s greater than 5 because it comes after 5 on the number line. Discuss relationships between numbers. Five is the middle because it’s halfway between 1 and 10. Five and five equals 10. Five is greater than 4, but less than 6 etc. Differentiation/Accommodations: Modify number lines. You can use number lines from 1-5 or 1-20 for higher levels. Primary Math Intervention Activities Columbus City Schools 2011-2012 Operations and Algebraic Thinking Primary Math Intervention Activities Columbus City Schools 2011-2012 Tic-Tac-Toe Tens Domain: Operations and Algebraic Thinking Cluster Statement: Understand Addition as Putting Together and Adding to, and Understand Subtraction as Taking Apart and Taking From Materials: Dry erase board Two different colored dry erase markers Directions: Students will practice adding and subtracting by ten in this game. One player designs tic-tac-toe board on dry erase board. The first player writes a 2-digit number in one of the spaces. The second player adds or subtracts one or ten to write a related number in one of the spaces. Each player takes a turn writing in numbers until there is a winner. The winner has three numbers correctly written in a row. For example, 25 26 27 35 36 37 45 46 47 The numbers in italics represent those chosen by Student A. The bolded numbers represent those chosen by student B. Differentiation/Accommodations: Allow students to use a hundreds chart as a resource. Primary Math Intervention Activities Columbus City Schools 2011-2012 Sums of Ten Domain: Operations and Algebraic Thinking Cluster Statement: Understand Addition as Putting Together and Adding to, and Understand Subtraction as Taking Apart and Taking From Materials: Playing cards (Ace -10) or numeral cards 0-10 White board Dry erase marker Erasers Directions: Students will choose top two cards from deck. They will add the two numbers and if the sum is ten a point is earned. Record points on whiteboard. If the two cards flipped do not equal ten, then no point is earned. Players continue to take turns flipping and adding their two cards. Player with the most points after all cards are flipped wins. Differentiation/Accommodations: You can change the number to fit whatever number bonds the class is focusing on that day. Primary Math Intervention Activities Columbus City Schools 2011-2012 Double Fun Domain: Operations and Algebraic Thinking Cluster Statement: Understand Addition as Putting Together and Adding to, and Understand Subtraction as Taking Apart and Taking From Materials: Paper Crayons or pencil Directions: Students will add doubles and identify sums that equal 20 by creating visual representations. Discuss different situations when students may need to double a number. For example, a child may need two teddy bear counters to play a game. How many would two children need? After brainstorming have students draw different animals or objects to create doubles posters. For example for 2’s students could draw two faces with eyes, for 5’s two hands etc. Differentiation/Accommodations: If 20 is too high have students create doubles posters to 10. Primary Math Intervention Activities Columbus City Schools 2011-2012 Domino Fact Families Domain: Operations and Algebraic Thinking Cluster Statement: Understand Addition as Putting Together and Adding to, and Understand Subtraction as Taking Apart, and Taking From Materials: Dominoes set Dry erase board Dry erase marker Directions: Students need to record and model fact families. Use dominoes to model the commutative property of addition. For example, show students using dominoes how 2 + 3 = 5 and 3 + 2 = 5. Give each student a domino with three dots on one side and two dots on the other side. Have students use different dominoes to model various number sentences. Students will record number sentences for at least five facts families under 10. Differentiation/Accommodations: Students could work with fact families under 5 or fact families 11-20 if they need more challenge. Primary Math Intervention Activities Columbus City Schools 2011-2012 Dominoes Domain: Operations and Algebraic Thinking Cluster Statement: Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from Materials: Complete set of Dominoes Directions: Play dominoes; only change the rules to one more or two more. For example, if a “3” is on the table, the students needs a “4” or “5” to make the play depending on if the rule is one more or two more. Differentiation/Accommodations: This activity should be played in small groups of 3-5. This lesson can be used to teach one less or two less in subtraction too! If students are not familiar with dominoes, start with teaching them the original game first to get them familiar with how to play. Primary Math Intervention Activities Columbus City Schools 2011-2012 Let’s Go Back Domain: Operations and Algebraic Thinking Cluster Statement: Represent and Solve Problems Involving Subtraction Materials: Unifix® cubes Directions: Make up a story problem. “There were 10 children in line. 3 children went to the office. How many children were left in line?” Give each child a 10 Unifix® cubes. Have each child count back 3 from 10 and take away 3 cubes. Tell children to count the remaining cubes. Discuss their answer. Try several different story problems using different numbers. Differentiation/Accommodations: Use smaller numbers for students that are beginning subtraction and larger numbers to challenge advanced students. This activity could be done with addition as well by telling students something has joined the group. Primary Math Intervention Activities Columbus City Schools 2011-2012 Race to Twenty Domain: Operations and Algebraic Thinking Cluster Statement: Represent and Solve Problems Involving Addition and Subtraction Materials: 2 ten frames for each child Tiles or another type of counter Spinner + or – (1st Grade Numeracy Board Resource Packet, p. 62) 1 dot cube for each student Pencil Paper clip Directions: Have each child roll a dot cube and place that number of counters on one of their ten frames. Then each child spins the spinner to determine if the operation is plus or minus. Then they roll the dot cube again to use that number to place or take away counters from their ten frames. Keep rolling the dot cube and spinning until a student reaches 20 exactly. If a student does not have enough counters to take away from their ten frames or tries to add too much to their ten frames, they lose their turn for that round. Differentiation/Accommodations: Younger students can just use one ten frame and call the game “Race to Ten”. Another differentiation could be to just add using the dot cube and not the spinner. You could also start with 10 or 20 counters and subtract using the number rolled on the dot cube. Primary Math Intervention Activities Columbus City Schools 2011-2012 How Much More Domain: Operations and Algebraic Thinking Cluster Statement: Represent and Solve Problems Involving Addition Materials: A cup and counters Directions: Put number counters in a line and cover up some with a cup (no more than 18). Have the students count the number of counters they see and then ask them “How many counters will I need to make ___?” Lift the cup to show them the counters they need to make the number after students have time to figure out the answer. Use different amounts of counters or use one number with different variations under the cup. Differentiation/Accommodations: Use smaller numbers with struggling students. Primary Math Intervention Activities Columbus City Schools 2011-2012 Construct It Domain: Operations and Algebraic Thinking Cluster Statement: Represent and Solve Problems Involving Addition Materials: Work mat Unifix® cubes Directions: Give each student the same number of Unifix® cubes and a work mat. Then have students break the Unifix® cubes into two parts. Write down and discuss the different combinations for that number. Make sure to write down all number combinations before moving onto another number. Differentiation/Accommodations: Make sure to use numbers below 10 for struggling students. You can also have advanced students break a number up into more than two parts. For a challenge you can use numbers greater than 10. Primary Math Intervention Activities Columbus City Schools 2011-2012 Are You Ready to Rumble? Domain: Operations in Algebraic Thinking Cluster Statement: Understand and Apply Properties of Operations and the Relationship between Addition and Subtraction Materials: Overhead projector/Document camera White boards and markers (1 per student) Directions: The teacher has the overhead/document camera set up at the front of the class. On it, she writes an addition or subtraction math fact, leaving out the operation sign. For example, 4 __ 5 = 9 or 10 __ 4 = 6 needs to be written on the overhead. Students will write the sign that goes into the math fact on their white boards then turn their white boards over. Next, once the teacher sees that everyone is ready, she says “Are you ready to RUMBLE?” Students hold up their white boards so that the teacher can see it. Have a student explain their thinking to the class. Repeat! Differentiation/Accommodations: Have students work in pairs and discuss why choose the addition sign or the subtraction sign prior to writing it down. Primary Math Intervention Activities Columbus City Schools 2011-2012 Opposites Domain: Operations and Algebraic Thinking Cluster Statement: Understand and Apply Properties of Operations and the Relationship between Addition and Subtraction Materials: Index cards (with addition/subtraction number sentences up thru 10) White dry erase board Dry erase markers Overhead projector/Document camera Directions: Teacher will create addition/subtraction number sentences on index cards up thru facts of 10. The teacher will pass out white dry erase boards and markers. The teacher will place a number sentence on the overhead projector or Elmo and the students will write a number sentence opposite of what they see. For example; the teacher displays 4 + 2 = 6, the students will have to write a subtraction (opposite of addition) number sentence for the same numbers 6 – 2 = 4 or 6 – 4 = 2. The student who gets the opposite number sentence correct first will win the card. The teacher will repeat this process using different number sentence cards. At the end of the activity, the student with the most cards wins. Differentiation/Accommodations: This can be done as whole group or small groups up to 5. To challenge your students create addition/ subtraction cards up thru 20. This can also be done with the students showing the teacher the opposite using manipulatives (teddy bears, centimeter cubes, colored tiles) showing part-part-whole or whole-part-part. Primary Math Intervention Activities Columbus City Schools 2011-2012 Flip It Domain: Operations and Algebraic Thinking Cluster Statement: Add and Subtract within 20 Materials: A deck of playing cards (remove all the face cards) Directions: The teacher will deal out all the cards between both players. The players will then organize their cards in their hands, as many as they can hold, the others will be in a stack in front of them face-down. One player will call out “FLIP IT" and at the same time both players will flip a card out of their hand and on to the table face-up. The first player who can add the two cards together correctly will get the set of cards. After all the cards have been flipped, then you can begin a new round. The winner of each round is the player with the most cards. Differentiation/Accommodations: This activity should be done in small groups of 2-3 students. This can be used to teach subtraction and helping the students understand that they have to subtract from the bigger number first. Teacher can choose to work with a smaller amount of cards instead of a whole deck for beginner practice. Primary Math Intervention Activities Columbus City Schools 2011-2012 Dirty Domino Dozens Domain: Operations and Algebraic Thinking Cluster Statement: Add and Subtract within 20 Materials: Set of Double-Six Dominoes Directions: Play dominoes. Place all dominoes face down so the dots can not be seen. The teacher will flip one domino at random. The first player flips a domino and joins the sets of dots on both dominoes. If the total number of dots on both dominoes equal 12 or a dozen, the player will keep both dominoes. If the total number dots on dominoes do not equal 12 or a dozen, the player will leave them face up on the table. The second player will flip one domino and looks for any face-up domino that could be joined with another face-up domino to make 12 or a dozen. If a combination of 12 or a dozen can be made, the player takes those two dominoes, if 12 or a dozen can not be made, the player will leave those dominoes face-up. Play continues to until all dominoes have been flipped face-up. The winner is the player with the most dominoes at the end. Differentiation/Accommodations: Focus on joining smaller sets of dots to equal numbers such as 4, 6, 8, and 10. For higher level students, have each student write an equation for each of their flips or look for higher combinations up to 20. Primary Math Intervention Activities Columbus City Schools 2011-2012 Bear Fact Family Fun Domain: Operations and Algebraic Thinking Cluster Statement: Add and Subtract Within 20 Materials: Bear Fact Resource Page (48 total bears 5-12) Craft sticks Tape Teddy bear counters Directions: Cut out the bears and tape each bear on a craft stick. All bears will be placed face down on the table. The first player will choose a bear and flip it over. The other player has to name two numbers that make up the number on the bear’s belly (they may use the teddy bear counters to help them decompose the flipped number). The player receives one point for each fact in the fact family that is named correctly. Players take turns choosing bears and naming facts in the fact family. The first player to reach 20 or more points wins. Differentiation/Accommodations: This activity should be done in small groups of 2-5 students. Teacher can choose to work with a smaller amount of bears instead of all 48 bears (ex. 5-10).

Domain: Operations and Algebraic Thinking Cluster Statement: Work with Addition and Subtraction Equations Materials: Laminated number lines (1-10) Dot cube (one, numbered 1-6) Cards numbered 1-9 Directions: Teacher will supply laminated number-lines to the group. The teacher will then pull a card and call out the number. The student will place a colored counter on the number. The teacher will then roll the dot cube and call out that number. The student will jump with his or her finger the number of spaces forward on the number line. The teacher will then ask key questions: • What number did we land on? • How many spaces did we jump with our finger? • Can we write an addition number sentence for these numbers? Repeat with using different number cards and dot cube rolls. Differentiation/Accommodations: This activity should be played in small groups of 3-5. This activity can be used to teach subtraction by moving backwards on the number-line! For groups that are lower start with number-line 1-5 and for group that are higher use number-lines 1-20. Primary Math Intervention Activities Columbus City Schools 2011-2012 What’s Missing! Domain: Operations and Algebraic Thinking Cluster Statement: Work with Addition and Subtraction Equations Materials: Linking cubes (12 for each player) Dot cubes (Two, numbered 1-6) Directions: First player will roll the dot cube, add the two rolls together and then call out the number. All players will then build a tower using the stated number. Once the towers are complete, each student will hold their tower behind their back and break it into two pieces. One at a time, each player will put one piece of their broken tower out in front of them. The other players will try to guess the missing piece. The first one to guess the missing piece correctly gets a point. Once all players have shown their towers, the round is over. Roll a new set of numbers for the next round. When the game is over, the student with the most points wins the game. Differentiation/Accommodations: This activity should be played in small groups of 3 or more. This activity can be used for teaching part-part-whole and subtraction. Primary Math Intervention Activities Columbus City Schools 2011-2012 How Many More Domain: Operations and Algebraic Thinking Cluster Statement: Work with Addition and Subtraction Equations Materials: Clear plastic jars Centimeter cubes Directions: Teacher will say, “Let’s count out 3 centimeter cubes and put them in front of us.” Students and teachers will count aloud 3 cubes together (1, 2, 3). Next, the teacher and students will place the “3” centimeter cubes in their jar and screw the top on tightly. Then the teacher will ask the students to shake the jar and say, “I have 3 cubes in the jar.” Teacher will then ask, “Can we count on using this jar. Watch. We don’t have to count these in the jar, because we already know how many we have, right?” Have individual students recall to the teacher how many cubes are in the jar. Now the teacher will ask, “If we add one cube, how many do we have altogether?” The students will put the cube next to the jar not in it. Without shaking the jar, see if the students can figure out they only have to add 1 to the 3 in the jar. Have the students yell out how many they have now (i.e., “I have four.”). Repeat with a different number up to 10. Differentiation/Accommodations: This activity should be played in small groups of 3-5. This activity can be used for teaching part-part-whole and subtraction. For higher level students do number up to 20. Primary Math Intervention Activities Columbus City Schools 2011-2012 Using Addition to Multiply Domain: Operations and Algebraic Thinking Cluster Statement: Work with Equal Groups of Objects to Gain Foundations for Multiplication Materials: Colored chips Number cards Directions: Give each student 20 colored chips. Explain the link of repeated addition to multiplication. Hold up a number card, for example 3. What is our answer if we double it, 3 + 3? Wait for students to discuss and get a unanimous answer of 6. Explain that they just multiplied 3 × 2 … two groups of 3. Move on to a new number card, skipping the addition step and see if they are able to multiply it by 2. This is best done in small group. Teacher asks a student for answer, if she/he is able to correctly answer then she/he receives the number card. If not, ask the student to check his/her work using the colored chips. The student with the most number cards at the end wins. ** Students can use colored chips to figure out answer. Differentiation/Accommodations: Use larger number cards. Have students multiply by 3 or 4. Primary Math Intervention Activities Columbus City Schools 2011-2012 Multiplication and the Zero Rule Domain: Operations and Algebraic Thinking Cluster Statement: Work with Equal Groups of Objects to Gain Foundations for Multiplication Materials: Colored chips Bags – Ziploc® or brown lunch bags Directions: Give each table/group a handful of colored chips and several bags. Teacher models a set number (e.g., 2) in one bag. Then, teacher puts the same number of chips in another bag. Ask the children how many chips we have in both bags. Do the children agree that we have 4 chips altogether? Discuss that we just multiplied 2 chips times 2 bags (2 × 2). Empty the bags. What would happen if we had 2 bags with 0 chips in each bag? How many chips would we have altogether? Does everyone agree that we would have 0 chips? Discuss that we just multiplied 0 chips times 2 bags (0 × 2). Repeat this step with 5 bags, 7 bags, and 0 chips. Why do we get the same answer? Is there a number that is staying the same? Differentiation/Accommodations: Use this game to illustrate a variety of multiplication situations (not just zero). Primary Math Intervention Activities Columbus City Schools 2011-2012 Multiplication and the Identity Rule Domain: Operations and Algebraic Thinking Cluster Statement: Work with Equal Groups of Objects to Gain Foundations for Multiplication Materials: Colored chips Bags – Ziploc® or brown lunch bags Directions: Explain the identity rule. Give each table or group a handful of colored chips and several bags. Model using one bag and placing chips (e.g., 4) in it. We have 1 bag and 4 chips, how many chips do we have altogether? Make sure everybody agrees on 4. We just multiplied 1 bag × 4 chips (1 × 4). Repeat steps with new numbers and have students follow along with their tables or groups. Discuss what the students noticed and whether they observed any patterns. Make sure all students understand the identity rule. Differentiation/Accommodations: Use this activity to discover other multiplication situations/story problems. Primary Math Intervention Activities Columbus City Schools 2011-2012 Number and Operations in Base Ten Primary Math Intervention Activities Columbus City Schools 2011-2012 Making Twenty Domain: Number and Operations in Base Ten Cluster Statement: Work With Numbers 11-19 to Gain Foundations for Place Value Materials: Ten frames, (2 per student) 10-20 numeral cards Two-color counters Directions: Each student needs to have two ten frames. Students draw a number card and construct the number on their ten frames. Teacher asks questions, “How far away from ten?” “How many more to make twenty?” Differentiation/Accommodations: Use one ten frame and numeral cards 1-10. Use three tens frames and numeral cards 20-30. Have students write down math facts that they discover while using one, two or three tens frames and their two-color counters. Primary Math Intervention Activities Columbus City Schools 2011-2012 Let’s Count by Tens! Domain: Number and Operations in Base Ten Cluster Statement: Work With Numbers 11-19 to Gain Foundations for Place Value Materials: 100 chart Ten frames Multiple of ten numeral cards Directions: Students count to 100 by 10’s while pointing to the numbers on the 100 chart. Student draws a multiple of ten numeral card, counts to that number while laying down a ten frame with each count. When the child is done counting, the teacher asks, “How many?” “How many tens?” Have the child note that in the number sixty there are six groups of ten and that the six ten frames show the same as sixty. Differentiation/Accommodations: Focus on numbers ten, twenty and thirty for an introduction. Use numbers thirty to one hundred thirty for an extension, use this as an opportunity to introduce hundreds place value. Primary Math Intervention Activities Columbus City Schools 2011-2012 Creating Groups Domain: Number and Operations in Base Ten Cluster Statement: Work With Numbers 11-19 to Gain Foundations for Place Value Materials: Collection of objects up to 20 (cubes, bears, double sided counters) Directions: Students count objects in a variety of ways (1’s, 2’s, 5’s, and 10’s). Ask how many groups of each and how many are not in a group. For example, if you have twenty counters, and count them by 5’s, you have four groups of five with zero left over. Differentiation/Accommodations: Try this game with a different number of counters. You can try an odd number for more of a challenge, a smaller number than twenty or a number larger than 20. Primary Math Intervention Activities Columbus City Schools 2011-2012 What is the Number? Domain: Number and Operations in Base Ten Cluster Statement: Work With Numbers 11-19 to Gain Foundations for Place Value Materials: Base ten blocks Two-color counters Index cards (3 per group) Crayons (3 per group) Directions: Ask children to give an example of ways they can represent an amount by using a word, a number, a tally mark or a model (base ten blocks). Hand out materials and tell students we are going to use the materials to represent the same number in multiple ways. Example: Teacher calls out the number 15. Give blocks to one child in a group, the counters to another, index cards to another and crayons to another child in the group. The two children with blocks and counters show how to make the number 15.

Primary Math Intervention Activities Columbus City Schools 2011-2012 Beans…Beans…Everywhere! Domain: Measurement and Data Cluster Statement: Measure and Estimate Lengths in Standard Units Materials: Dried beans (5 per student all different sizes, and types) Pencils Rulers Measuring tapes Yardsticks Student Recording Sheet Literary Connection: Jack and the Beanstalk Directions: Read Jack and the Beanstalk. After reading the story, tell students they will get a magic bean to practice their measurement skills. Teacher will need to talk about and review vocabulary such as; inches, centimeters, yard, foot, length, distance and estimation. Teacher will explain to the students that they will be flicking their beans from their area, recording estimates, and doing actual measurements. Teacher will demonstrate these steps first. Students will flick their beans, write down an estimate of how far they think it traveled, and then do an actual measurement with a ruler, tape measure, or a yardstick (the key is the student has to decide what to use according to their estimation and the distance they think their bean has traveled). After students have completed 10 trials with flicking their beans and recorded their measurements, the group can talk about the different distances, estimations, and the different tools they used to measure. Questions a teacher may ask are; • Why are there differences in our measurements? • Why did I use a ruler and not a tape measure or yardstick? • What bean type went the farthest, and why do you think that? Differentiation/Accommodations: Students can be divided into 2 teams. Each team can be assigned a bean bag, pencil and a clipboard. The teams will have a start and a finish line. The first teams to reach the finish line with all the correct recordings (estimate measurement and the actual measurement) recorded correctly using the right tool wins.

Domain: Geometry Cluster Statement: Reason with Shapes and their Attributes Materials: Set of basic shape manipulatives Teddy bear counters Directions: Pair students in groups of two and give each group manipulatives – one of each shape and a handful of teddy bear counters. Instruct students to place the square on the table and put one teddy bear counter on each side of the square. Ask, how many teddy bear counters are placed on your square? How many sides does a square have? Instruct students to place one teddy bear counter on each vertex of the square. Ask, how many teddy bear counters are placed on your square? How many vertices does a square have? Instruct students to repeat steps with the triangle and circle. Discuss how many teddy bear counters are on the circle. Why do you not place teddy bear counters on the circle? Differentiation/Accommodations: Have students explore the sides and corners of more complex shapes such as a trapezoid, hexagon, octagon, etc. Primary Math Intervention Activities Columbus City Schools 2011-2012 What Shape Am I? Domain: Geometry Cluster Statement: Reason with Shapes and their Attributes Materials: Set of attribute blocks Directions: Place a set of attribute blocks in the center of each table. Create descriptive riddles in order to get your students to guess the correct shape that you are thinking of. Once the students think they know the shape that you are thinking of, have your students choose the shape and hold it up in the air. Give more descriptions in order to rule out some of the shapes that were picked. Examples: 1.) I am a shape with no vertices or sides 2.) I am blue, thick, and have three sides 3.) I am a shape that has four sides, but not all of my sides are equal Differentiation/Accommodations: Give more or fewer details in order for the students to guess the correct shape. Have students create a set of clues for a specific shape. Primary Math Intervention Activities Columbus City Schools 2011-2012
