- A pack of cards (with face cards left out).
WALT: Use inverse operations to find numbers.
WILF: Using known elements to find the unknown (algebra).
Game Objective: To work out your number.
This game is to be played in groups of three (one dealer and two players rotating the roles).
- The dealer gives each player a card which they hold on their forehead without looking at it.
- The dealer tells the two players the sum, product, or difference of the two numbers.
- Players must work out what their card is, by listening to the total and looking at the other player’s card.
For more of a challenge, play with three players and a dealer.
