Objective: Model the equivalence of tenths and hundredths using the area model and number disks.
In Lesson 5, students relate hundredths to the area model, to a tape diagram, and to number disks. They see and represent the equivalence of tenths and hundredths pictorially and numerically. Students count up from 1/100 with number disks just as they did with centimeters in Lesson 4. This time, the 10 hundredths are traded for 1 tenth, and the equivalence is expressed as 1/10 = 10/100 = 0.1 = 0.10 (4.NF.5, 4.NF.6). The equivalence of tenths and hundredths is also realized through multiplication and division.
