The area model can do more than build Spatial Reasoning. It can help make sense of the major multiplication and division strategies! In this episode Pam and Kim use a Problem String to show how reasoning about area can build more sophisticated and efficient multiplicative relationships.
Talking Points:

Multiplication is about grouping groups
The area model can help make sense of multiplicative relationships and properties
Choose and celebrate efficient strategies
Reasoning about area makes relationships pop so that the strategies are natural outcomes!
