Lesson 7 Concept Development

Problem 1: Determine that multiplying the numerator and denominator by n results in an equivalent fraction.
Problem 2: Given an area model, determine an equivalent fraction for the area selected.
Problem 3: Express an equivalent fraction using multiplication and verify by drawing an area model.
Each rectangle represents 1 whole.

Lesson 7 Problem Set

1. The shaded unit fractions have been decomposed into smaller units. Express the equivalent fractions in a number sentence using multiplication. The first one has been done for you.
3. Draw three different area models to represent 1 third by shading. Decompose the shaded fraction into (a) sixths, (b) ninths, and (c) twelfths. Use multiplication to show how each fraction is equivalent to 1 third.

Lesson 7 Problem Set 2

2. Decompose the shaded fractions into smaller units using the area models. Express the equivalent fractions in a number sentence using multiplication.
