The CCSS-M are designed around coherent progressions from grade to grade.
Each standard is not a new event, but an extension of previous learning.
Learning is carefully connected across grades so that students can build new
understanding onto foundations built in previous years. But what do teachers
do when that foundation is not there? In this session we will share engaging
teacher tested games, tasks, and stations designed to help students build and
strengthen their mathematical foundation. The activities from our session will
help to build students’ procedural fluency and conceptual understanding.

Never “Bored” Game
Directions
1) On your white board or chalk board trace a
sheet of paper over and over going up and
down again creating a game board type
pattern.
2) On the board game write movement directions for students. Examples:



You got it correct, move up 2.
Switch places with another group.
Going too fast, move back 5.
3) Place students on teams of 2-4 people. Each team will have a magnet that they
will move across the game board. (You can make each magnet a famous
mathematician, for example on group could be Einstein, or Pythagoras)
4) Have groups write their names on notecards or if you already use popsicle sticks
or notecards to call on students you can use those. You might want to only have a
single notecard for each team though.
5) All groups must work together and try all of the problems.
6) I give the class a problem to solve. Each group works together to solve the
problem. Groups can do their work on white boards or in their notebooks.
7) After some time, I tell the groups to put their markers down. I pick a few teams
to show me their answers. If they are correct, they roll one of my giant foam
cubes (or any dice would work) and then that groups moves their magnet the
correct number of spaces.
Tips
1) I make sure the students know that they
must follow what the game board says, so
if they land on switch places and they are
actually in the lead, they still must switch
with someone.
2) I usually make the end square say
something about them doing so great but
that they must go back to the beginning
and start again. The students will ask
when the game will end then and I just tell
them it ends when I’m ready for it to end
(based on time and if we finished the
review)
3) Sometimes groups keep track of how
Benefits
1) Every student is engaged and solving
every problem
2) Students are working together and
are able to help each other
3) Great formative assessment. I tell
which students need help and which
type of problems are giving the class
difficulty
4) Great review before tests or quizzes
5) Kids have fun moving along the
game board and they think it is fun
to be the “magnets”
6) Teacher prep can be very easy; you
can just pick random questions from
many times they go through the board to
“determine the winner,” but we usually
don’t worry about who wins. Of course
you can give a small treat to the winners if
you want, but I really try to emphasis the
effort and not who won.
4) I pick multiple groups for each question
to keep all groups engaged. I also keep
every groups card in the pile. Students
never know if they will get picked or not,
so they must all try every problem. I also
keep the number of groups picked
random; sometimes I pick 2 groups or 4
groups. I think this randomness keeps all
groups on track. It can make the game
“unfair” in that some groups get called on
more than others, but since “winning” isn’t
our focus it is fine.
5) I have played were every group that gets
the answer correct gets to roll the dice and
move, but that can get a little crazy, but it
does then keep the game “fair” and then
every group shares their answer every
time.
your book and ask those. If for some
questions though the students need
to see the problem or problems I just
cut and paste some review problems
from the book and put into a Smart
doc, still very quick prep.
Wheel-Of-Mathematics
Directions:
Teacher creates teams of students. Teams can be two large teams or smaller groups of
4-5 students each. Teacher asks a question, students answer, and teacher randomly
picks a student’s name to see if they have the answer correct for their team. If student
is correct, they get to spin. If student is incorrect, the next team steals the question and
the teacher picks students from another team.
Rules:
1. All students must try each problem even if it is no their turn in order to be ready for
the steal. If a team member is not trying, the team forfeits their turn.
2. Poor sportsmanship results in a loss of points. For example, if a team teasing that the
spinning team only earned one point on their spin then the team may double the points
earn.
3. In the case that a student gets a question wrong, the teacher will never say who.
Benefits:
*The game can be mixed up each time you play so the game has new twists and turns
*Can be used for any subject and unit-we have played created spinner game in
Language Arts and Math
*Can be differentiated by separating team in multiple ways
*Position struggling students by choosing their name when they have a question
correct.
*Students like digital spinners on Smart Boards but they LOVE spinners they can
actually feel
*Students do not see who answers the question correct and who does not
*Students walk away with several review questions
*Encourages sportsmanship
Other Game Ideas:
Anything pretty much can be turned into a board game. I’m sure most of us have
played trash can basketball or Smartboards are great for “Jeopardy” and “Koosh ball”
games. My students love playing all sorts of games. Some of our favorites are:
Magnet Darts:
Years ago I found a magnet dart board at a dollar store
and it has been a classroom favorite ever since. I
usually just put the class into two teams, usually boys
against girls, but you can do whatever. I explain that
our darts are magnets, so they don’t have that exact
point like darts, so we don’t play with the doubles and
triples on the dart board and if we really can’t tell what
number it landed on, we will always pick the larger
number.
 I have notecards with each student’s name
written on it and I divide those cards into the
two teams. (Again I usually sort boys and girls
but you can just “deal” the cards into the two
teams.)
 I give the class a problem to solve. They can
solve on white boards or in their notebooks. (They tend to love the white boards,
but sometimes I have them do in their notebooks so that they can use this to
review or study for a test.)
 After some time, I pull a notecard and have that student share their answer. If
correct they get 10 points just for being correct and then they get to throw the
dart to add to their points. Students mark the points on the board.
 Every student must try every problem, since they never know whose card will get
picked. If a student answers incorrectly, the other team gets to “steal” and try to
answer. Even once a card is picked; it still goes back in my pile, so that every
student knows they could get picked. (I still control whose card gets picked so I
can determine how to best “help” students with special needs. Since I’m walking
around as they work, I will often pick a student who struggles only after I saw
that they have it correct on their sheet.
Tic-Tac-Toe
Another game the students love is tic-tac-toe. We play this game a few different ways.
I have an old “Toss Across” game that has students toss bean bags at a game board that
spins to reveal either a “X” or an “O.” I also bought a tic-tac-toe beach towel game from
Oriental Trade. This is just a towel with the game board on it and students toss either
their “X” or an “O” at the towel after answering. The fun part of both of these is that
sometimes they can’t control were their “X” or an “O” lands or if a “X” or an “O” will
flip over in Toss Across. This really puts an interesting twist to tic-tac-toe and then if
often won’t end in a “cats” game. We also sometimes play the traditional way and just
draw the game board and place our “X” or an “O” on the board. (This is the best way
when we don’t have much time.)
Benefits:
 Again every student is involved
 Great formative assessment
 Easy teacher prep
Bowl-A-Fact
Start by rolling three dice. This is your first
“throw” down the lane.
1) The students must use all three and only those three
numbers rolled to try to knock down as many “pins”
as possible. To knock down a pin, the pin number needs to be the answer to the
problem the students create. I put the pin sheet on the Smartboard and as we knock
down the pins, we cross them out.
2) To knock down a pin students can add, subtract, multiply, divide, use fractions,
exponents, etc. BUT again they must use all 3 and only those 3, so you can’t have 32
unless you rolled both a 3 and a 2.
3) Goal: to work together as a class to try to get a strike.
4) After a few minutes of work time, students can come up to board and share their work
for a pin that they knocked down. Students will discuss if they agree with the work and
if they “knocked” down that pin a different way. (Often as they are working, they will
say aloud, “I got the 4 pin.” Or “I can’t get 8, did anyone get the 8?” etc. I encourage
this type of talk. I often work on it too and will tell them if I got a number they need,
but I don’t tell them how. Since all totals are not possible with three numbers I don’t
want them to try forever to get something they can’t get, but I also don’t want them
giving up with something can be knocked down.)
5) If we don’t get a strike, we throw again looking for the spare. A throw is rolling the
three dice. Now, we only have to try to get the pins that are still standing. If we
knocked down the five on our first roll, we don’t have to get that answer again.
EXAMPLE
Roll #1
4–2–3
Possible work:
32 – 4= 9-4 = 5, knocked down the 5 pin
24 ÷ 3 = 8, knocked down the 8 pin
4 + 3 +2 = 9, knock down 9
4 – 3 + 2 = 3, got the three
etc.
Great for working on order of operations. Often students get a pin, but without ( ) it
might not be correct, so we work on that.
Roll #1
Roll #2
Add It UP
Directions
Create four problems for each team of four
students. Each student is assigned a number and
will complete the matching problem. When all
students have finished their problem, their team
adds up all four answers, writes the sum in the center, and raises their hand.
If the team’s sum is incorrect the teacher will simply let the team know to rotate the
board. Students rotate the board and work together to find the error. Students pose questions
about their peer’s work to better understand where their final answer came from and share if
they have a critique. In the rare case that no errors are found, students can rotate the board
until the error is found. Students add their new answers together, place the new sum in the
center, and raise their hand to signal they are ready for the teacher to review their work.
If the team’s sum is correct, the teacher asks the team to cover their answer and “teach” their
group their problem if they haven’t rotated the board yet. Another option is to send one
student from the finished group to each of the unfinished groups as “coaches”.
Once a stopping point presents itself, have different groups share out their solutions one
problem at a time.
Tips
*Before sending “coaches”, students need to practice asking questions to guide their peers to
the answer and not just tell struggling students the final answer.
*Require students to be able to explain their own problem so no one student can take over.
*When appropriate, try to require all four students to understand all problems in the
group. Interview students on questions that they were not assigned to before telling a group if
they are correct or not.
*When playing multiple rounds, rotate the type of question that each student receives.
Benefits
*Create
leveled problems to meet the needs of all
students
*Each student has a critical piece in the activity- all
students have equal value as a member of the team
*Individual work and team work in one activity
*Students work together to critique and understand
all problems
*Students’ perseverance in problem solving is strengthened

Zip It!
Directions:
Students are in groups of two. Partner 1 is the only one that can write for
the team and needs to ZIP IT! Partner 2 is the only one that can speak.
Partner two explains what partner 1 should write. No erasing can be
done unless the speaker requests it. The student writing cannot write an
assumption but must wait for specific directions.
Example: A student cannot say write the number in order from least to greatest.
They must say “first write 10, now write 11” etc.
The partner writing can use the Zip It cards as a way to communicate.
The writer can point to either “Can you repeat that?”, “Why?”, or “How do
you know?” as a way to move the speaker along or slow them down if
needed.
tips:
Practice! This takes lots and lots of practice. Model this activity with
examples and non-examples.
Highlight moments when this really helped students develop a stronger
understanding and soon enough students will request this when they
know they need to work breaking down content.
benefits:
This allows teachers to hear all voices and allows students to explain
EXACTLY what they’re thinking. Students can see the importance of
precise math language
This helps students to slow down their thinking and gives students
practice on giving their peers the “think time” needed.

Boaler, J., & Staples, M. (2008). Create mathematical futures through an equitable teaching
approach: The case of Railside School. The Teachers College Record, 110(3), 608-645.
Line it Up
Your group will get a set of notecards (white and a color.)
 The white cards will be your “benchmark” fractions, place them out in front of the
group leaving room in between (think of your spacing)
0,

 The colored notecards will have the fractions from the first box on them. You
will then take turns picking and then placing your notecard down in
the correct place based on your benchmarks on the number line you
are creating. When you place your notecard, you must explain
why you chose that location.
 If your group can not decide if you are correct based on your reasoning, discuss
and see if you can all agree on the correct placement. If you still are not sure use
your calculator and make it into a decimal, does that help? If not, ask me.
 When your group finishes the first box, write the correct answers below. Then
come up to get another set of colored cards and work on the second box, etc.

Tangram Task
TASK: You will be demonstrating your ability
to write and reason in math. If all
seven
tangram pieces equal one whole-you need to
figure out what fractional part each piece
represents.
Your answer must be complete!
YOU NEED TO EXPLAIN YOUR REASONING.
(You only get one point for having the correct
answer-the rest is based on your explanation of how you got
that answer.) I should be able to tell exactly what you did to
solve the problem and what you know. You should also prove
that your answer is correct. You can use diagrams, phrases,
equations, or sentence.

Tangram Fractions
Task
Find the fractional part of each Tangram piece in the whole (All seven pieces). Be sure
to explain your reasoning
Purpose
This task allows the teacher to plan for future units on fractions. This task also involves a whole that
is divided into pieces that are not the same size. The more students play around with different
concepts of “whole” and “parts,” the better their understanding of fractions will be.
Context
This is one of the first tasks that I give to my students. I start by giving them a sheet that has them
making their own Tangram pieces by folding and cutting paper. Once they make their Tangram
pieces they keep them in their folders throughout the school year. They need their pieces because
sometimes as a warm-up for class we will do Tangoes puzzles. I also like doing this one first because
most of the students can do this. The students start off confused and want more direction, but with
time, most can figure it out for themselves. This helps them to feel more positive about problem
solving. I know the students have studied fractions in previous grades and I want to get a feel for how
many had a conceptual understanding of a fraction and how it relates to the whole. The task itself
does not name any of the shapes. I used to create a table for the students and had them just put in the
answer, but I decided to let them use their mathematics language and name the shapes themselves. I
also like that they need to decide how best to represent their answers than just filling in my table.
Solutions
Large triangles (#’s 1 & 2) = 1/4
Medium triangle, square, parallelogram
(#’s 3, 5, & 7) = 1/8
Small triangles (#’s 4 & 6) = 1/16

Biggest Bang for Your Buck
You have decided to give your math teacher a little treat to show her how much you
appreciate her. You have decided to buy her a candy bar as a small token of thanks (a
bigger gift will come later on in the school year  ) The cafeteria sells 7 different candy bars
all of which are the same thickness. You want to show your math teacher how much you
have learned in math class by purchasing the candy bar that is the best value. If all the
candy bars are $.50 each, how can you show that you picked the candy bar that is the
most chocolate for the smallest price? Explain two ways that show that you got the
“biggest bang for your buck.”

Hit the Trail
How to:
1.) Fold 10 (or more-as many sheets as you want questions)
pieces of construction paper in half (hamburger style) and staple a
plastic page protector sheet to the inside of your folded paper. (I
used brown for a “trail” type of look and created a cover page that
I glued to the front of the construction paper, and then I laminated,
so I just write on a new answer any time I play.)
2.) Write questions and slip them in the page protectors (a
different question for each folder)
3.) Write Answer to NON-matching problem on the outside
4.) Also number the papers on the outside as in #1-10
*I just used questions from our book so I didn't have to take time to make new
questions/answers.
5.) Hang problems up around the room so only the answer/outside shows
6.) Hand students *a problem to start with* (a number 1-10 that would work as their
starting place. this keeps all the goofballs from picking the same starting area and you can
level the questions to have struggling students at the easier problems)
Students start at their problem assigned. Once they complete the problem, they find the
matching answer to the problem they just solved and then complete the problem that it
led them to. If their answer is nowhere to be found- it means they did something
wrong. Students can work independently or with the people who are at the same
question.
I didn't really think that kids would like this because it really is just
answering problems...but they loved being able to navigate their way through the
room. When I stopped and listened to them- they really were all working and talking
about the problems.
I did this for equations and changed all variables to "a" so students couldn't just figure out
what the answer was by matching up the variable.
Math Maze: Directions
Directions: Create review problems for students. Place one problem on each page towards the
bottom of the page so you can fold over the front to “hide” the problem. On the front of each
problem, write the answer to the problem before it. In order to not have students caught in a “loop”
or be sent to the same problem more than once; make sure you only have each answer listed once
and create a rotation with your answers as modeled below. Create as many or as few problems as
needed!
Math Maze: Tips
*Assign students a starting place.
*Require students to show their thinking for each problem.
*Mix the problems up so the answers do not go in order...this creates more of a scavenger type feel to
the game!
*Spread out problems that require more time to prevent “traffic jams”.
Math Maze: Benefits
*Students self-check their work by instantly knowing if they are correct and retry problems.
*Students can practice at their own pace.
*Students work in independently or in partners.
*You are free to help students.

Lost Your Marbles
Directions:
Create practice problems to have at each station. Each station has an answer
folder and a cup for marble. Each pair of students is given as many marbles as
you have stations/questions. (You can do as many or as few of stations as you
want. I usually do this as a review and then my number of stations is the
same as my number of learning targets.)
Students work in partners and put a marble in each cup when they answer
correctly.
Students travel throughout the stations in numerical order.
Students answer each problem before checking their work.
When they check their work, they use the following KEY:
Put an X through problems you got correct (don’t have to study what you know)
and place your marble in that cup
Put a ? by the problems that you needed some help with but if you got it correct,
you can still put in the marble
Put an ! by the problems that you HAVE TO STUDY. Don’t put your marble in this
cup then!
Tips:
* Assign students a number to start at and have them
travel around the room. This elminates having chatty
students from picking the same questions to start at.
*Make sure students show all their work on their
sheets. This creates a great study guide for them.
*If you only have a few questions you want the
students to do, just create multiples of that answer
folder to keep students from all gathering at one
station. (So for example, if I only have 6 different
questions, I only have 6 stations, but I might have 4 of
the same folders at each station.)

Put an ! by the problems that you HAVE TO STUDY. Don’t put your marble in cup.
Directions:
Create practice problems to have at each station.
Students travel throughout the stations in numerical order.
Students answer each problem before checking their work.
If students have the correct answer, then they put the
question/slip of paper in the bag since they have it “in the bag”!
If students have the incorrect answer, they take the question
with them to study or re-try. If students need to check the
answer key before solving (because they are stuck), then they
take the problem with them.
Tips:
* Assign students a number to start at and have them travel
around the room. This elminates having chatty students from
picking the same questions to start at.
*Make sure students put their names on each problem that
they put in the bag. The first time you play, remind students
throughout the activity to do this so you know what each
student acomplished.
*At the end, have students walk around to any station that they
didn’t get to so they practice all problems.
*Have students write the answer to the problems that they had
incorrect or didn’t complete so they can self check later on as
well.
Benefits :
* You instantly see just how many students are on track
* Each question is a quick snapshot of student’s thinking
*Bags/questions that are empty or have few correct answers
need more attention
*Students work at their own pace
*Students take problems home that were incorrect and know
what they need to study
*Peers do not see who gets the questions right.
Two of a Kind: Directions
Create two problems that have the same answer and give
one to each partner. Students solve their own problem and
wait until their partner finished. Once both partners are done,
students compare their answers. Students cannot continue
onto the next problem without their partner.
Students share their problem and discuss how they solved it.
Students should discuss similarities between the two
problems.
If students have different answers, they help each other find
the error(s).
Two of a Kind: Benefits
*Can be used for a partner station, game, or parent-student
homework.
*Can be leveled to meet each student’s need-You can pair like
ability together or different abilities together and match ability
with the correct problems
*Students practice giving their peers the “think time” needed.
*Students critiques the work of others.
*Students compare differently representations and see
multiple problem solving methods

Top 3 Game Changers
Of all of the new things we have tired or worked on over the years, the three that have had
the greatest impact have been:
1) Math Talking Stems (the bookmarks)
2) My Favorite No (see sheet and check out the video link)
3) What Stuck With You?
If you try anything from our presentation, we strongly recommend these three things!
Math Talking Stems
(bookmarks)
Working on classroom discourse is huge. We know that we need to get students talking about
math. We found that the talking stems help the students know how to start discussions and
how to keep the talking more focused on the math. We make the bookmarks on card stock,
laminate, and give to the students early on in the school year. We have found that you need
to teach the students how to talk like mathematicians and the talking stems seem to help.
What Stuck With You?
1) I create a display with numbered squares for each student in my class. I used “library
pockets.” I glued them to poster board and then laminated the board. I used an exacto
knife cut back open the pockets.
2) Each student is given a math number. This number is used when they use my calculators
and it is their number for “What stuck with you?” (I used just have students put their
names on it and some students said they didn’t like having their name it. They wanted it to
be more confidential.
3) I often use this as a type of warm-up or as an exit question. I give the students a problem.
They solve it either on notecards that they tuck in the pocket or
on post-its that they stick to their number.
4) The great part with the numbers, I can easily check that all
students did the problem.
5) I then can use their answers to form my instruction. I can use
it to help group the students, use it to know which students
need to work with me, see if there are any misconceptions that
I need to clear up, use as example work that I can have the
students discuss (see My Favorite No), etc.
6) Also, students use it to just write thoughts, questions, or ideas
that they might have on a lesson that day. Students can grab a
post-it and write anything that “stuck with them” from that
day’s lesson.
My Favorite No
(by Leah Alcala)
One of the biggest changes we have added to our classroom this year has been
our work on discourse. We want students to talk about their math.
(CCSS.Math.Practice.MP3 Construct viable arguments and critique the reasoning of others.)
One idea that we used came from watching this video on “My Favorite No.”
https://www.teachingchannel.org/videos/class-warm-up-routine
The teacher featured in this video link is Leah Alcala, an eighth grade teacher
at Martin Luther King Middle School in Berkeley, CA. She gives her students a
warm-up problem at the beginning of every class, which they solve on index
cards. She quickly sorts through them, and from the wrong answers chooses
her "favorite no." She and her kids then analyze what's right about the
solution before delving in to what the writer doesn't do correctly.
We don’t use it daily, but both of us have done this with our students and they
love it. They have commented that they learn so much more from going over
incorrect answers than from looking at correct solutions.
Roller Derby
Objective: The students will explore experimental and
theoretical probability.
Supplies: Roller Derby overhead, homework overhead, Roller Derby sheets for each
student, 15 cubes for each student, and a pair of dice
Vocabulary:
probability: the chance of an event occurring
theoretical probability: the probability of an event is equal to the number of favorable
outcomes divided by number of possible outcomes
experimental probability: a statement of probability base on the results of a series of
outcomes
Procedure: The teacher will put the overhead of Roller Derby on the projector. The teacher
will read through the overhead with the students and will explain to the students how to
play the game. The teacher will make sure that all of the students understand the rules
and will give them some time to place their 15 cubes. The teacher will explain that once
the game starts the students can NOT change the placement of the cubes. The teacher will
then either roll the dice, or pick a student to role the dice, or pass the dice around the room
and allow all the students a chance to roll the dice. The two dice will be announced and
the students will then find the sum. Any student who has a cube on that sum will
“remove” their cube. Play will continue in this manner until someone removes all 15 of
their cubes. The first student to remove all their cubes is the winner. The teacher can then
give the winner a small piece of candy if they chose. You will then have all the students
clear off their cards and play again! (if time, you can play again and again  .) The teacher
can then lead a discussion about what strategies the students chose.
Homework: The students will then complete the Roller Derby reflection sheet. They need
to use complete sentences.

Roller Derby Reflection
Using complete sentences answer the following
questions.
1. Did it seem like “some of the sums” were rolled more than others? Why?
Explain the probability of rolling each of the sums.
2. When you played the game a second time, did you change where you placed
your cubes? Why or why not?
3. Do you think this is a game of luck or strategy? Explain.
Playing Fair
Parker Brothers, makers of such great board games as Monopoly, Sorry,
and Clue, have enlisted your help. They are in the process of
developing a new board game and they need for you to use your math
skills and check it out. First you should play the game a few times
with a partner and then you should develop a report to present to the
company.
How to play the game:
 First get with your partner
 Then decide which player will be who. One player will be Even Steven and the
other player will be The Odd Ball.
 Each of you will have a six sided number cube. You will each roll your die. Write
down the number you both got, then you need to multiply the numbers on the
dice, and record the product. [product: is the answer you get when you multiply
the two dice]
 If the product is even-Even Steven gets a point. If the product is odd-The Odd
Ball gets a point
 Do this twenty times and then total up the points. The player with the most
points after twenty rolls WINS!
 Record your results.
 Repeat the experiment and play again to determine if your results are the same.
 Finally prepare your report for Parker Brothers. Is this a fair game? Are you
“Playing Fair?”
