How to Play: Close to 100 Math Card Game

• Step 1: Deal 6 cards to each player. Place the deck face-down (draw pile).

• Step 2: Take turns. Use any four of your cards to make two 2-digit numbers. Try to make numbers that when added together give you a sum that is close to 100. 

  • Write these two 2-digit numbers and their total on the score sheet.

  • For example, a 6 and a 5 could be 56 or 65.  

• Step 3: Find your score: The score for the round is the difference between the sum and 100. 

  • For example: If your sum is 96, then your score for the round would be 4 since it is four away from 100. 

• Step 4: Put the four used cards in the discard pile and draw four new cards from the draw pile. 

  • If you run out of cards before the end of the game, shuffle the discard pile and use those cards again.

• Step 5: Five rounds make one game. After five rounds, total your score. 

  • The player with the LOWEST score is the winner.
