Lesson 7 Non-unit Fractions on the Number Line

    • Let’s locate non-unit fractions on the number line.

Warm-up Choral Count: One-fourths

Count by , starting at .
What patterns do you see?

Activity 1 Number Line Scoot

Now you will play a game where you move, by fractions, along different number lines. To start, each player places a small cube on zero on each number line. The goal of the game is to get as many small cubes as you can to the 4 on any of the number lines.

Activity 2 Fractions on the Number Line

  1. Locate and label and .

    Number line. 0 to 2 by ones. Evenly spaced tick marks. First tick mark, 0. Last tick mark, 2.
  2. Locate and label and .

    Number line. Evenly spaced tick marks labeled zero, one, and two.
  3. Locate and label and .

    Number line. 0 to 2 by ones. Evenly spaced tick marks. First tick mark, 0. Last tick mark, 2.
  4. Locate and label and .

    Number line. 0 to 2 by ones. Evenly spaced tick marks. First tick mark, 0. Last tick mark, 2.
  5. How did you partition the number line when you were locating the numbers and ? Explain your reasoning.

  6. What patterns did you notice in the fractions you located?

Activity 3 What’s the Fraction?

Students working together.
  1. Partition the number line into any number of equal-size parts. Locate and mark, but don’t label, a fraction of your choice.

    Number line. Evenly spaced tick marks labeled 0, 1, and 2.
  2. Trade number lines with a partner.

    1. How did your partner partition their number line?

    2. What number did your partner mark on their number line? Explain your reasoning.

  3. If you have time… Play the game again.

    Number line. 0 to 2 by ones. Evenly spaced tick marks. First tick mark, 0. Last tick mark, 2.
    Number line. Evenly spaced tick marks labeled 0, 1, and 2.

Practice Problem

Problem 1

  1. Locate and label on the number line.

    Number line. Evenly spaced tick marks labeled 0, 1, and 2.
  2. Locate and label on the number line.

    Number line. Evenly spaced tick marks labeled 0, 1, and 2.
  3. Diego marks and labels fourths on the number line like this:

    Number line. Tick marks labeled 0, 1 fourth, 2 fourths, 3 fourths, 1, 4 fourths, and 2. Larger space between 4 fourths and 2.

    Do you agree with Diego? Explain your reasoning.
