standard_description: Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). (Excludes compound units such as cm^(3) and finding the geometric volume of a container.) Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem. [Excludes multiplicative comparison problems (problems involving notions of “times as much”)]

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.
