Objective:  Transition from four partial products to the standard algorithm for two-digit by two-digit multiplication.

Lesson 37 deepens students’ understanding of multi-digit multiplication by transitioning from four partial products with representation of the area model to two partial products with representation of the area model and finally to two partial products without representation of the area model.
