Unit 6, Lesson 5# Model the equivalence of tenths and hundredths using the area model and place value disks

EngageNY 60 min(s)Support for English Language Learners

In this lesson, students examine hundredths using area models, tape diagrams, and place value disks. They shade several fractions on a hundredths chart to show the relationship between tenths and hundredths. Then they count by hundredths using place value disks, trading 10 hundredths for 1 tenth and writing the equation 1/10 = 10/100 = 0.1 = 0.10. Finally, they create equivalent decimal fractions using multiplication and division (for example, 1/10 x 10/10 = 10/100 and 10/100 ÷ 10/10 = 1/10), establishing that 1 tenth is 10 times as much as 1 hundredth.
