Section 1
Estimate the Magnitude of Scaling
Property
The closer a scaling factor is to 1, the closer the product will be to the original number. The farther a scaling factor is from 1, the more the product will change from the original number.
In this Grade 5 Eureka Math lesson from Chapter 24, students learn to compare the size of a product to the size of its factors when multiplying by fractions and decimals, discovering that multiplying by a factor less than 1 shrinks the product, greater than 1 enlarges it, and equal to 1 leaves it unchanged. Students practice scaling with both fraction and decimal forms such as 97/100 and 1.01, building understanding of how the value of the scaling factor determines whether the product is less than, greater than, or equal to the original. The lesson connects fraction-to-decimal conversion and real-world scaling problems to reinforce these comparison concepts.
