More than/Less Than
Number of Players: 2 players
Materials Needed: 2 dice
How to play: Each player will use 1 dice. Both players roll
their die at the same time. Both of the players look at the
dice and determine who has more, who has less, or if they
have an equal number of dots on their number cubes (dice).
The players will say the statement that applies:
“I have more than you.” "I have less than you." "We are equal.”
I Have Morel
Number of Players: 2 players
Materials Needed: 2 dice
Counters (beans, cheerios, fruit loops, M & Ms)
How to play: The players take turns rolling the number —
cubes (dice) and adding the numbers represented by the
dots on their cubes. The player who has the highest sum
takes a counter. The winner is the first player to get ten counters.
Parents: When your child first starts to add the dots on the two dice they will probably count
them all, this is typical. Eventually your child will begin to realize that they are adding
numbers and may be able to compute the sum of the two dice in their head.
How Many?
Number of Players: 2 players
Materials Needed: 2 dice
2 napkins or paper towels
1 bowl of cereal
How to play: The first player rolls both dice and removes the cereal
indicated by the dice and places it on his/her napkin. The second
player rolls his/her dice and puts the indicated number of cereal
pieces on his/her napkin. The players should take turns until each of
them has completed 10 turns. The players then count the cereal in
each pile. The player with the most cereal is the winner.
Dice Games
Which Number Wins?
Math concepts: In this individual activity, students roll two dice and record
the results. Make a recording sheet that is an 11 x 12 block grid with the
numbers 2 through 12 across the bottom. While young children gain
practice with addition facts, older children can examine the data, and think
about why some sums are more likely than others.
Materials: two dice and a recording sheet
The object: to roll the dice and record the number fact in the correct
column, stopping when one number gets to the finish line.
After you've collected the data, discuss with the class why it seems that
some sums "win" more than others.
Snakes:
Math concepts: Students of all ages can play this game, as long as they're
able to add the numbers that come up on two dice. While younger children
benefit from the practice of adding, older students have the opportunity to
think about the probability of the sums from rolling two dice.
Materials: Two or more players can play. A piece of paper with the
numbers 2 to 12, expect 7 written on it. Here are the rules for playing:
1. Players take turns rolling the dice. When you roll the dice add the two
numbers together. Cross out the number on you paper — the other player
does not cross out the number. If that number has already been crossed
out do nothing. |
2. If you roll a 7 draw a snake on your paper. If you get seven snakes on
your paper, you are out of the game.
3. The winner is the first player to cross out all the numbers on his paper or
the only player without seven snakes.
Tie-Fact-Toe _
Materials: paper, pencil, 2 dice, red pen and black pen
Object: To be the first player to get three in a row and gets the point in that
round. You can play as many rounds as you would like.
How to play: Draw a regular tic-tac-toe grid. Choose nine numbers from 2 to 12
and put one in each space. Do not repeat numbers.
One player uses the black pen and one player uses the red pen. Take turns
rolling the dice. When it is your turn, add together the two numbers on the dice.
If your answer is on the grid, put an “X” through it with your pen. Then the other
player rolis the dice and does the same thing.
Pia
Materials: one pair of dice, pencil and paper
Object: To be the first to get a score of 100 or more
How to play: Draw two column on a sheet of paper. Label one with your name
and one with your partner's name.
Players take turns. When it is your turn, roll the dice as many times as you like,
keeping a running total of what you roll. Don’t write down the sums, but add them
mentally and say them aloud so your partner can check.
When you decide to stop rolling, record the total for that round in your column.
If a 1 comes up on one of the dice, your turn ends, and you score zero for that
turn. if dice show 1s, your turn ends and your total score so far goes to zero.
Card Games
Place value war-
Players divide the playing cards evenly between themselves. Each player turns
over two cards to create a 2-digit number. The number on the first card turned
over represents the number that will appear in the tens place; the number on the
second card represents the number that will appear in the ones place.
Both piayers call out their numbers. (You might have them verbalize: "Six tens
and two ones equals sixty-two.”) The player with the largest number gets all four
cards.
In the event of a tie (if each player has the same 2-digit number), war is declared.
First, each player places three cards face down.
Then each player tums over two more cards and adds the second number
created by those cards to the first number.
The player with the largest sum gets all of the cards.
Variation: Players turn over three cards and build numbers into the
hundreds.
Grade 2: have players compare their second number to the first (figure the
difference) instead of finding the sum.
Make 20:
Skills: Adding/Subtraction, Odd/Even, and number line:
Materials: Grades 1 - 2: playing cards Ace (= 1) through 5
Grades 2 - 3: playing cards Ace (= 1) through 9
paper and pencil
Each player makes a gameboard that looks like this:
01234567891011121314151617 181920
Each player begins the game at number 10 on their gameboard. The goal of the
game is to get to 20 or O.
Each player turns over one card from the deck of cards. That number determines
the number of spaces the player can move on their gameboard.
If Player 1 draws an odd-numbered card, he must subtract and move backward
from his current place on the gameboard. He must move back (left) the
number of spaces indicated on the card.
If Player 2 draws an even-numbered card, she must add and move forward
from her current place on the gameboard. She must move ahead (right)
the same number of spaces indicated on the card.
The first player to reach a score of exactly 20 or zero is the winner.
Teachers can use this game to introduce the concepts of number lines and
number lining.
Subtraction war
Materials: playing cards Ace (= 1) through 10
Players divide cards evenly between themselves. Each player turns over
two cards and subtracts the smaller number from the larger number. The
player with the smallest answer wins all four cards.
Example:
Player 1 draws a1 anda 9. (9-1 = 8)
Player 2drawsa2 and a7. (7 - 2 = 5)
Player 2 collects all four cards because she has the smallest answer.
In the event of a tie (if each player has the same answer), war is declared.
Each player deals out three more cards face down. Then each player turns
over two more cards and subtracts the numbers on those cards. The
smallest answer wins all of the accumulated cards.
Play continues until one player has collected all of the cards in the deck.
Variations: Add or multiply the two cards and the player with the biggest
number wins
Fishing for Ten
Materials: playing cards Ace (= 1) through 9
Deal all cards to players. Each player looks through hand and makes pairs
of cards that sum to 10. Place pairs face up in front of each player. Take
turns asking one another for a card that will make 10 with a card in your
hand.
Example: If you have a 7 in your hand, ask: “Do you have a 3?”
If the player has the card asked for, it must be given up. The player keeps
asking for cards until he/she is told, “| don’t have that.” The goal is to get
the most pairs that add to 10.

Teaching Addition Math Facts to Kids With Go Fish!
This new twist on the old classic Go Fish! helps kids to learn addition by mentally working out
simple math problems. Each round played practices math facts for a specific number, making 1t
easy to stick with one set of facts for as long as needed to solidify them in the players” mind.
All that’s needed to play this game 1s a standard deck of playing cards. 1H 15 best enjoyed with 2-4
players.
How to Play Go Fish!
1. Sort through the deck to remove all cards that are higher than that featured number for the
math game. For example, if the goal is to learn addition facts for the number seven, the game
will be played with ones {aces} through sevens.
2. Deal out five cards to each player and place the remaining cards in a draw pile.
3. Have each player look through his or her hand of cards to find any pairs that add up to the
featured number and place them face up in their discard pile. For example, if learning addition
facts for the number seven, appropriate pairs would be 6+1, 5+2 or 4+3. The 7 card would also
be laid aside as a correct solution that doesn’t require a pair.
4. The person to the left of the dealer may now ask any other player for a card that will help create
the sum required. If the person asked has the card in his hand, he must give it up to the player
that made the request. A player can keep asking for cards until no further matches are able to
be made, at which point he is told to Go Fish! from the draw pile and the next player takes a
turn trying to make a match.
5. If a player runs out of cards he can choose five more cards from the draw pile to stay in the
game,
6. Continue playing until all the cards in the deck have been matched inte pairs. The player with
the highest number of pairs at the end of the game is the winner.
Learning Addition Facts by Playing Memory
The card game Memory, or Concentration, is another great game that can be modified to teach
addition facts to kids. As with the instructions for Go Fish! above, each game focuses on math
facts for a specific number.
All that’s needed to play this game is a standard deck of playing cards. It can be played alone or
with a group.
How to Play Memory
1. Sort through the deck to remove all cards that are higher than that featured number for the
math game. For example, if the goal is to learn addition facts for the number six, the game will
be played with ones (aces) through sixes.
2. Shuffle the deck and turn all the cards face down in a grid pattern.
3. Taking turns, have each player flip two cards to look for a matching pair. For example, if learning
addition facts for the number six, appropriate pairs would Бе 5+1, 4+2 or 3+3. The 6 card would
also be laid aside as a correct solution that doesn’t require a pair.
4. Continue playing until all the cards in the deck have been matched into pairs. The player with
the highest number of pairs at the end of the game is the winner.
Subtraction “War”
Play this fun card game with your child and before long those challenging subtraction math facts
will be part of her mathematical skill set. Besides strengthening subtraction skills, this game also
provides practice in comparing numbers. Y our teacher will thank you: in school, second graders
are spending lots of time going up and down the number line, counting objects, and developing
deep understanding of these all-important number concepts.
What You Need:
e Deck of cards
e Kitchen timer
What You Do:
1. Shuffle the deck of cards and deal them face down, giving each player an equal number of cards
until the deck runs out. Each player keeps his cards in a stack. Assign picture cards, such as jacks,
queens, and kings, a value of 10. Give aces a value of 1.
2. Demonstrate to your child how to play the game: Each player turns two cards face up, reads the
number sentence and supplies the answer. For example, if your child draws a 5 and a 4, he says
5 -4= 1. lfyou draw a 7 and an 2, then your number sentence is 7-2 = 5. Because your result is
larger, you win the four cards and you put them at the bottom of your pile.
3. Mf each of you has a number sentence with the same answer, then it's war! At this point, you'll
reverse the math "operation" and do an addition problem. Each player puts four cards face
down and turns up two of them. The player with the sum wins all eight cards.
4. Setup the timer and play the game for 10 to 15 minutes. When the bell goes off, each player
counts his cards. The player with the most cards wins. If one player runs out of cards before
time is up, then the other player wins.
Get your game on! Subtraction Math War is an marvelous, high-speed way to build up math
skills while spending a richly enjoyable time with your child.
Ten-Twenty-Thirty
Try this single-player addition game! All you need is a deck of playing cards to get started. Try
to find sums of 10, 20, or 30 in order to clear cards. Practice your adding, and double check your
work. If you can clear all of the cards, you'll win! "Ten-Twenty-Thirty" is a great way to have
fun while practicing simple addition facts. After you've mastered the directions, check out the
variations for new ways to play.
Skill:
What You Need:
es One deck of playing cards (Print a deck.)
What You Do:
1. Shuffle the deck. Create a row of seven cards, face up. Place two cards on top of each of the
seven so you have seven piles of 3 cards each. Arrange the cards so you can see the face value of
every card.
2. Place the rest of the deck to the side, to be used later.
3. The object of the game is to remove a pile when the sum of all of its cards is 10, 20, or 30. All
face cards equal 10. For example, if a pile has an ace, 9, and jack in it, it could be removed
because its sum is 20 (1 + 9 + 10). Go ahead and remove all of the piles that equal 10 to start.
4. Deal a fourth card on top of every pile that remains. Remove any stacks that now equal a
multiple of 10.
>. Deal a fifth card on top of every pile that remains. Remove any stacks possible.
6. Continue adding cards and removing stacks until your deck is depleted or the stacks have all
been removed.
7. Ifyou remove all the stacks first, you have won! If your deck is emptied first, try again.
Variations:
Remove two sets of cards at once if their combined sum is a multiple of 10.
e Look for different sums, let's say 9, 19, and 29. Or multiples of 6

Pile it On: A Multiplication Game
Introduce multiplication to your child using a deck of playing cards and a die. This game
provides an excellent demonstration of how multiplication works. First, players roll the die twice
to find numbers for their multiplication fact. Then, they place cards in piles to create a visual
representation of each fact. When solving their problem, players can count the cards or use the
multiplication facts they already know. As patterns appear within the game, players will gain a
better grasp on multiplication.
What You Need:
e One deck of cards [Print a deck.)
e One die (Make your own.)
e A score sheet for every player (Print these out.)
es Pencils
What You Do:
1. On a player's turn, they roll the die twice. Their first roll indicates how many piles they must
make. Their second roll tells how many cards to place face down in each pile.
2. The player will then create those piles, add up the total number of cards used (either by
counting them or by using multiplication), and record their score.
3. Play for ten rounds. The person who uses the most cards total is the winner.
(rive this fun addition game a try! Challenge your child to create sums as close to 100 as he can,
without going over. This requires him to evaluate all possible sums, based on the numbers he is
given. He'll learn common patterns in addition as he works out the best plays, Try talking
through the game with your child, asking him what he's thinking as he selects cards, and making
discoveries together!
What You Need:
e Deck of cards
e Paper and pencils {for scratch paper)
e Close Call score sheets (Print these out.)
What You Do:
1. Remove 10s and face cards from the deck. Shuffle the deck and deal each player 6 cards.
2. Each player selects four of their cards and creates two 2-digit numbers from them. The goal is to
create two numbers that have a sum as close to 100 as possible, without going over.
o (For example, a player may choose to use the cards 4, 6, 8, and 1, creating the problem
14 + 86 = 100.)
3. After players have made their selections, they place their cards face up in front of them,
arranging them so other players can see which two numbers they have created.
4. The player with the numbers closest to 100, without going over, wins a point. In the case of a
tie, a point is awarded to each team.
Shuffle the cards before dealing another round.
6. Play continues for 5 rounds. The player with the most points after the last round wins the game.
