How should context and models be used to build strategy? In this episode, Pam and Kim share a sequence of tasks regarding area to demonstrate a better approach for building understanding, abstraction, and strategy as a natural outcome.

Talking Points

• Hand2mind Foundations for Strategies
• Use of manipulatives to feel the meaning of area
• Guiding students to become more sophisticated, both in models and in strategies
• The importance of context for clarity and developing strategy
• Moving from concrete, to representational, to abstract to deepen understanding, strategy, and independence, NOT to apply an algorithm
