Exploring Multiplication with Partial Products

The video tutorial covers lesson 2.7 on multiplying using partial products. It explains the four steps involved: expanding numbers, distributing, solving for partial products, and adding to find the final product. The tutorial also includes estimation techniques by rounding numbers to the greatest place value. Several example problems are solved to demonstrate these methods, and homework problems are addressed to reinforce the concepts.
