Unit 6, Lesson 12

Apply understanding of fraction equivalence to add tenths and hundredths

EngageNY 60 min(s)

In this lesson, students decompose tenths using the area model and place value chart to add tenths and hundredths. They also use multiplication to generate equivalent fractions and express the sum in fraction form as a decimal. (For example, they add 3/10 + 4/100 by replacing one number with an equivalent: 30/100 + 4/100 = 34/100 = 0.34.) Finally, they add tenths and hundredths in cases where the sum is greater than 1.
