Unit 3, Lesson 38# Transition from four partial products to the standard algorithm for two-digit by two-digit multiplication

EngageNY 60 min(s)

In this lesson, students continue to develop their understanding of the standard algorithm for multiplication through area model, partial products, and the distributive property. Students then progress to using partial products and the standard algorithm. The multiplication problems continue to be two-digit by two-digit problems, but they also require compositions in the tens and hundreds place when determining the partial products.
