In this Grade 4 Eureka Math lesson, students learn to identify and represent patterns when multiplying by 10, 100, and 1,000 using place value disks and place value charts. They explore how multiplying shifts digits one place to the left for each factor of 10, connecting repeated multiplication (such as 3 × 10 × 10) to single expressions like 3 × 100. The lesson also reinforces group counting by multiples of 10 and 100 to build fluency with place value relationships.
Section 1
Place Value Shifts when Multiplying by Powers of 10
When multiplying a number by , , or , every digit in the number shifts to the left on a place value chart. The number of places shifted corresponds to the number of zeros in the multiplier: one place for , two for , and three for .
