Lesson 5 Concept Development
Problem 1: Simplify hundredths by division.

Problem 2: Model hundredths with an area model.

Problem 2: Compose hundredths to tenths using number disks and then represent with a number bond.

Problem 3: Use numbers disks to represent a decimal fraction.
Write the equivalent decimal in unit form.

Lesson 5 Homework
1. Find the equivalent fraction using multiplication or division. Shade the area models to show the
equivalency. Record it as a decimal.

2. Complete the number sentences. Shade the equivalent amount on the area model, drawing horizontal
lines to make hundredths.

3. Circle hundredths to compose as many tenths as you can. Complete the number sentences. Represent
each with a number bond as shown.

4. Use both tenths and hundredths number disks to represent each number. Write the equivalent number
in decimal, fraction, and unit form.
