Lesson 11 Concept Development

Problem 1: Use a tape diagram and a number line to find equivalent fractions for halves, fourths, and eighths.

Problem 2: Use a number line, multiplication, and division to decompose and compose fractions.

Problem 3: Decompose a non-unit fraction using a number line and division.

Lesson 11 Problem Set 1

1. Label each number line with the fractions shown on the tape diagram. Circle the fraction that labels the point on the number line that also names the selected part of the tape diagram.



Lesson 11 Problem Set 2

2. Write number sentences using multiplication to show
a. the fraction represented in 1(a) is equivalent to the fraction represented in 1(b).
b. the fraction represented in 1(a) is equivalent to the fraction represented in 1(c).
Lesson 11 Problem Set 3

3. Use each shaded tape diagram below as a ruler to draw a number line. Mark each number line with the unit fractions shown on the tape diagram, and circle the fraction that labels the point on the number line that also names the selected part of the tape diagram.

4. Write number sentences using division to show
a. the fraction represented in 3(a) is equivalent to the fraction represented in 3(b).
b. the fraction represented in 3(a) is equivalent to the fraction represented in 3(c).
Lesson 11 Problem Set 5

5. a. Partition a number line from 0 to 1 into fifths. Decompose 2/5 into 4 equal lengths.
b. Write a number sentence using multiplication to show what fraction represented on the number line is equivalent to 2/5.
c. Write a number sentence using division to show what fraction represented on the number line is equivalent to 2/5.
