Grades 4 and up
- multiplying 2-digit numbers
- playing cards Ace (=1) through 9
- paper and pencil
Each player begins the game by drawing four cards from the deck. Players arrange their cards to make a 2-digit multiplication sentence. The object is to make the largest product possible.
- Player 1 draws the cards 9, 6, 4, and 2. He forms the sentence 94 x 62, which results in a product of 5,828.
- Player 2 draws the cards 8, 7, 4, and 2. She forms the sentence 84 x 72, which results in a product of 6,048.
Player 2 has the largest product in that round. She scores 1 point.
Play continues. Each player draws four new cards and calculates the product of the multiplication problem they create.
The first player to score 9 points (for nine innings) is the winner.
Players should write out all problems and check each other's work.
- Change the game's rules so that the smallest product wins.
- Let students use calculators to check their answers.
