Narrative
Before playing, students remove the cards that show 10 and set them aside.
Each student picks 4 cards and chooses 2–3 of them to use to create a multiplication expression. Each student multiplies the numbers. The score for the round is the difference between each student’s product and 100. Students pick new cards so that they have 4 cards in their hand and then start the next round. The player with the lowest score wins.
Variation:
Students can write the related division equation for each multiplication equation they record.
