Task# Extending Multiplication From Whole Numbers to Fractions

Illustrative MathematicsVaries

This task can be used at the beginning of a fourth grade unit on multiplication with fractions to evaluate what students know about multiplication. After knowing how students understand multiplication and the different diagrams they use, the teacher can better integrate their prior knowledge into future lessons about fraction multiplication. For the first two questions, the goal is to see what students know about the meaning of multiplication based on how they represent multiplication with contexts and diagrams versus simply having strategies to solve multiplication problems.
