Multiply by multiples of 10 using the place value chart

EngageNY 60 min(s)Support for English Language Learners

In this lesson, students use the place value chart to multiply by multiples of 10. To solve 2 × 40, for example, they begin by modeling 2 × 4 in the ones place. Then they relate this to multiplying 2 × 40 (or 2 × 4 tens), where the same basic fact is located in the tens column. They conclude that when multiplied by 10, the digits in the product shift one place value to the left.
