Learning by Doing

Objective: To reinforce the concept of addition, subtraction and absolute value of
integers.
Materials required: Zero Game Sheet (below) for each player, 1 deck of playing
cards per group of students (3 to 4 students per group)
Procedure:
• Red cards represent negative numbers, black represent positive numbers and consider
face cards, i.e., Jack, Queen, King and Aces as 11, 12, 13 and 1 respectively (depending
on what you need).
• Distribute each player 2 cards. One facing up and a hidden one facing down.
• Each player adds up their cards to see if they are close to zero. Otherwise they can say
“Give me a card” and get another card. They can get up to FOUR cards but must use all
of their cards in their final total. They can also HOLD at two cards.
• Once everyone is finished being “Hit” all cards are turned over. Each player writes all of
their cards down and then adds up their total in the total box. The player with the smallest
total wins the hand and gets to be the dealer!
• Each player finds the absolute value of their total in the absolute value column.
• When time is up, each player adds up the absolute value column. The person closest to
zero wins the game!
