Multi-Digit Multiplication Strategies

Currently we are learning to multiply multi-digit numbers using three related strategies.

Area Model:

Partial Products Algorithm:

Distributive Property:
We have been working on two, three, and four digit numbers times one digit numbers, but will also use these strategies to multiply two two-digit numbers.  

All of these strategies are important in helping students develop the place value understanding necessary to comprehend and successfully perform the multiplication standard algorithm.  Problem-solvers are always working toward more efficient strategies, so I will introduce the "traditional" way to multiply multi-digit numbers later this year.
