Fractions on Number Lines
Est. Class Sessions: 1Summarizing the Lesson
Display the Show That Fraction master. Ask a student to choose a fraction, and represent it using symbols, words, the two fraction strips, drawings, or the number line from 1 to 2. Then ask other students to come up and represent the same fraction using one of the other models including a drawing of any shapes they choose. See Figure 4. Continue until several fractions have been represented.
As each student shows his or her representation, ask:
Encourage students to use the terms numerator and denominator in their explanations. For example, a student may show a number line divided into fourths and say, “The 4 in the denominator told me to divide the number line into fourths. The 5 in the numerator told me to count 1/4, 2/4, 3/4, 4/4, 5/4 and put a point there.”
