Lesson 4 Concept Development
Problem 1: Use tape diagrams to represent the decomposition of 1/3 as the sum of unit fractions.
Problem 2: Use tape diagrams to represent the decomposition of 1/5 and 2/5 as the sum of smaller unit fractions.
Problem 3: Draw a tape diagram and use addition to show that 2/6 is the sum of 4 twelfths.
Lesson 4 Problem Set 1
1. The total length of each tape diagram represents 1 whole. Decompose the shaded unit fractions as the sum of smaller unit fractions in at least two different ways.
