Grades 4 and up
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 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.
