Lesson: Multiplying Three-Digit Numbers by One-Digit Numbers: Adding Partial Products Mathematics • 4th Grade

Start Practising

In this lesson, we will learn how to multiply three-digit numbers by one-digit numbers by calculating partial products and using expanded column multiplication.

Lesson Plan
