Description
What are the five major strategies for multiplication? In this episode Pam and Kim name and give examples of each of the five major multiplication strategies. If students own these strategies they should be able to solve any multiplication problem that is reasonable to solve without a calculator. They will be able to solve it as efficiently as a traditional algorithm and most of the time more efficiently than the traditional algorithm. But even more important than that, they will be developing Multiplicative Reasoning!
Talking Points:
- Smart Partial Products
- Over/Under
- 5 is Half of 10
- How are these strategies related to the distributive property?
- Doubling/Halving
- How is this strategy related to the associative property?
- Using Quarters & Scaling
- Bonus! Flexible Factoring
