Beat the Calculator (Addition Facts)
Materials: Number cards – 40 cards (4 each of numbers 1 – 10)
Number of players: 3
Directions: One player is the “caller,” a second player is the “calculator,” and the third player is the "brain."
1. Shuffle the deck of cards and place it face down on the playing surface.
2. The caller turns over the top two cards from the deck. These are the numbers to be added. The calculator finds the sum with a calculator, while the brain solves it without a calculator. The caller decides who got the answer first. Players trade roles every 10 turns or so.
Variation 1 - Beat the Calculator (Multiplication Facts): Players multiply the numbers on the two cards.
Variation 2 - Beat the Calculator (Extended Multiplication Facts): The caller attaches a 0 to either one of the factors or both factors.
If the caller turns over a 4 and a 6, he/she may make up one of the following problems:
4 * 60
40 * 6
40 * 60
Name That Number
Materials: Make up a deck of number cards from an ordinary deck of playing cards, as follows:
- For the numbers 2 through 10, use the 2 through 10 cards.
- For the number 1, use aces.
- Write the number 0 on the queens’ face cards.
- Write the numbers 11 through 18 on the remaining face cards (kings, jacks).
Number of players: 2 or 3
Directions: Shuffle the deck of cards and deal 5 cards to each player. Turn over the top card. This is the target number for the round. Players try to name the target number by adding, subtracting, multiplying, or dividing the numbers on as many of their cards as possible. A card can only be used once. They write their solutions on a sheet of paper or slate. Then they set aside the cards they used to name the target number and replace them with new cards from the top of the deck. They put the target number on the bottom of the deck and turn over the top card. This is the new target number. Play continues until there are not enough cards left in the deck to replace both players’ cards. The player who sets aside more cards wins the game.
Players' numbers: 7, 5, 8, 2, 10; Target number: 16
Some possible solutions (cards used are in bold):
7 x 2 = 14 --> 14 + 10 = 24
--> 24 - 8 = 16
(four cards used)
8 ÷ 2 = 4 --> 4 + 10 = 14
--> 14 + 7 = 21
--> 21 - 5 = 16
(all five cards used)
