Lesson 24 Homework
Use fractions strips and number bonds to show that 1 whole = 2/2 =
3/3 = 4/4 = 6/6 etc.
1. Write number bonds as indicated. Partition and label the number line to show the unit fractions of the
number bond. Don’t forget to rename the 0 and 1 as fractions of the given unit.
2. Circle all the fractions above that are equal to 1. Write them in a number sentence below.
3. What pattern do you notice in the fractions that are equivalent to 1? Following this pattern, how would
you write the next whole as a fraction?
4. In an Art class, Mr. Joselyn gave everyone a 1 foot skewer to measure and cut. Vivian broke hers into 5
equal pieces, and Scott broke his into 7 equal pieces. Scott said to Vivian, “The total length of my stick
must be longer than yours because I have 7 pieces and you only have 5.” Is Scott correct? Use words,
pictures, or a number line to help you explain.
