Grades: 4‒5

Students add and subtract fractions with like denominators on a number line to reach a variety of target numbers. Students must build the fractions using only a specific list of values as numerators and denominators. Can students find more than one way to reach each target number by adding and subtracting different fractions? Students develop strategies for finding multiple solutions.

OBJECTIVES

- Students will add and subtract fractions with like denominators.
- Students will develop strategies for adding and subtracting fractions to reach a given target using given numbers as choices for numerators and denominators.
