Lesson 14 Representing Fractions on a Line Plot

    • Let’s make a line plot and analyze the data we collect.

Warm-up Which One Doesn’t Belong: Line Plot

Which one doesn’t belong?

  1. Dot plot from 0 to 4 by 1’s and hash marks at fourths. Beginning at 1, the number of X’s above each half increment is 3, 0, 5, 0, 0, 2.

Activity 1 Sums of Fractions

  1. Play Sums of Fractions with your partner.

    • Take turns with your partner.

    • Spin the spinner twice.

    • Add the two fractions.

    • Record the sum on the line plot.

    • Play the game until you and your partner together have 12 data points.

    Spinner. 4 equal parts. Labeled 1 half, 1 fourth, 1 eighth, 5 eighths.
    Number Line. Scale 0 to 2, by 1’s.
  2. How did you know where to plot the sums of eighths?

  3. What is the difference between your highest and lowest number?

  4. What do you notice about the data you collected?

Activity 2 Lots of Eggs

Image of scale for weighing eggs.
  1. Use the egg weights listed to make a line plot.

    Horizontal line, not labeled.
  2. Jada said that of the eggs weigh   ounces. Do you agree? Explain or show your reasoning.

  3. How much heavier is the heaviest egg than the lightest egg? Explain or show your reasoning.

Practice Problem

Problem 1

Here are the lengths of some pieces of ribbon measured in inches:

  1. Complete the line plot with the ribbon lengths.

    Horizontal line. Not labeled.
  2. What is the sum of the lengths of the ribbons that measure more than 4 inches? Explain or show your reasoning.
