ADDITION/SUBTRACTION 12 Card Draw Materials: Deck of cards (take out all the 10’s and face cards) 1. Place 12 cards face up and the rest face down in a pile. 2. Each player takes turns taking the top card from the pile and tries to match it to a card face up to make ten. If you are able to remove a card, replace it with one from the pile. If you cannot remove a card, place the card you drew from the pile to the side. 3. The player with the most matches at the end wins. ADDITION/SUBTRACTION Go Fish Materials: Deck of cards (take out all the 10’s and face cards) 1. Each player receives 7 cards to begin with. 2. Begin by players looking through their hands to see if they have combinations of 2 cards that will add to 10. If they do, the cards go down as matches. 3. Play begins by players taking turns asking other players for numbers they need to make pairs of cards adding to 10. 4. If they get a pair, they place it aside. If not, they “Go Fish” and choose a card from the center pile. 5. The game is over when no more pairs can be made. 6. The winner is the person with the most pairs of cards. ADDITION/SUBTRACTION Face Off Materials: Deck of cards (take out the face cards) 1. Find two friends to play; you need three players. 2. Shuffle the cards and place them face down between the players. 3. Two players face off by taking one card from the top of the deck and placing it against their forehead. Each player should see the other player’s card but not their own. 4. The third player says the sum of the two numbers out loud. 5. The first player to say the number on their forehead wins both cards. 6. Continue play by rotating who plays and who is the “adder” until all cards have been used. 7. The player with the most cards wins. **This game can also be played by finding the difference between the two cards. The third person would be the “subtractor.” ADDITION/SUBTRACTION Addition Quick Draw Materials: Deck of cards (take out the face cards) 1. Deal out the entire deck so that both players have an even number of cards. 2. One player calls, “Draw” and both players turn over their top card and place it face up in the center. 3. The players add the two cards that are showing and the first player to say the correct sum out loud wins the two cards. 4. After all cards have been used, the players count the number of cards that they have won. The winner is the person who has the most cards. **This game can also be played by finding the difference between the two cards. ADDITION/SUBTRACTION The Game of Pig (Addition) Materials: a pair of dice 1. Take turns rolling the dice and adding the sums. 2. On your turn, roll the dice as many times as you like. Each time, add the dots on the dice and keep a running total of the sum of your rolls mentally. You decide when you want to stop rolling and record the sum on a piece of paper. However, if you roll a 1 on one of the dice, your turn is over and 0 is scored for that round. If 1s come up on both dice, your turn is over and your total for the game becomes 0. 3. The first person to reach 100 wins. ADDITION/SUBTRACTION Subtraction War Materials: Deck of cards (face cards can be viewed as the number 10 or removed from the deck) and counters (pennies, beans, macaroni, dry cereal) 1. Deal out the entire deck of cards evenly between two players. 2. Each player turns over the top card from his or her deck. The player with the larger number takes the two cards and as many beans or counters as the difference between the two numbers turned over. Thus if 6 and 4 are turned over, the player who turned over 6 gets to take 2 beans because 6 subtract 4 is 2. 3. If the same card is turned over by each player, two more cards are turned over and the player with the larger number takes all of the cards and the number of beans equal to the difference between the second set of cards turned over. 4. The game is over when one player has no cards left. 5. The winner is the player with the most beans. ADDITION/SUBTRACTION Differences and Dice Materials: Deck of cards (take the face cards out) and a die 1. Place 9 cards face up and the rest face down in a pile. 2. Each player takes turns first rolling the die. The number rolled becomes that player’s target number. I can take ___ and ___ because 3. Look for two cards that have a difference the same as their difference is ____. the target number. 4. If you are able to remove a pair, replace them with two from the pile. If you cannot remove a pair, your turn is over. 5. Play continues with each player rolling the die and looking for that difference. 6. The player with the most matches at the end wins. **Challenge: Have each player turn two cards over and find the sum of the cards. The player with the larger sum takes all four cards and the number of beans equal to the difference of the two sums. ADDITION/SUBTRACTION Addition Top-It Materials: Deck of cards (face cards can be viewed as the number 10 or removed from the deck) 1. Deal out the entire deck of cards evenly between two players. 2. Each player turns over the top two cards from his or her deck and adds them together. 3. The player with the larger sum takes all four cards. If the same sum is turned over by each player, two more cards are turned over by each and the player with the larger sum takes all of the cards. 4. The game is over when one player has no cards left. ADDITION/SUBTRACTION Subtraction Pig Materials: Pair of dice 1. Players start out with 100 points each. 2. Players take turns rolling the dice and subtracting the resulting number from his remaining points until a 1 appears on any dice rolled. That player’s turn ends, and the next player takes a turn. 3. When a player has lost all of his points, he is out of the game. 4. The last player in the game is the winner. ADDITION/SUBTRACTION The Sum What Game Materials: Pair of dice and number cards 1-9 (pull the ace through 9 of one suit from the deck of cards) 1. Player one rolls the dice and adds the numbers together. 2. Player one can turn over the sum or any combination of 2 numbers for that sum. For instance, if you roll a sum of 9, you can turn over the 9 or any combination of 9 (8,1; 2,7; 3,6; 4,5). 3. Player 2 rolls and turns over either the sum or a combination of the sum. If a card has already been turned over, it cannot be used and is out of play. 4. When a player cannot play the turn, they are out and receive a score of the sum of the remaining cards face up. 5. The player with the lowest score after 5 rounds wins.
