This Problem Set is a part of the Lesson 5, Unit 6, Grade 4. 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.
