Model Multiplication with Place Value Disks
Property
Multiplying a single digit by a multiple of a place value unit can be modeled by creating equal groups of place value disks. This relationship can be expressed as:
In this Grade 4 Eureka Math lesson, students learn to multiply multiples of 10, 100, and 1,000 by single-digit numbers by recognizing place value patterns, such as understanding that 2 tens × 4 = 8 tens and 2 hundreds × 4 = 8 hundreds. Students use place value disks and unit form to connect basic multiplication facts to larger units, building fluency with problems like 8 × 20, 8 × 200, and 8 × 2,000. This lesson is part of Chapter 10 and develops the foundational understanding of how the number of zeros in a product relates to the place value of the factors.
