Task
Review this handout that describes types of multiplication situations.
For each type of multiplication problem listed in Section 3.1b of your digital handout, draw a diagram to represent both the semantic structure of the problem (e.g. the way the situation is presented) and its context (e.g., the details of the situation).
Compare your drawings with others in your group.
Discuss
- What similarities and differences do you observe?
- Do some diagrams more faithfully represent the situation than others?
- How might this help students better see the operation in the problem?
