Around the World
Domain: Counting and Cardinality
Cluster Statement: Know Number Names and the Count Sequence
Materials:
Number cards to 100 (These may be written on index cards or use
numbers big enough for the students to see from a short distance.)
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.

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.

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
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.

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.

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.

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.

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.

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.

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
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.

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.

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.

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.

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.

Domain: Operations in Algebraic Thinking
Cluster Statement: Understand and Apply Properties of Operations and
the Relationship between Addition and Subtraction
Materials:
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.

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
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.

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.

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.

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).

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
• 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!

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.

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.

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.

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).

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.

describe the attributes of the shape including color, size, thickness,
number of sides, and number of corners. Instruct the same student to
reach into the bag pull out another shape that is congruent to the first
shape they pulled out. (Explain/discuss the meaning of congruent
shapes.) Make sure the shape has the same number of sides and corners
to confirm that it is congruent. Repeat these steps with the other student.
Differentiation/Accommodations:
Have students reach into the bag and grab a shape. Instruct students to
identify the shape without looking at it but by feeling the sides and
corners.

How Many Sides/Corners?
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.

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.
