Grades: 3‒4

Students construct and add fractions with the same denominators on a number line to find different combinations of fractions that sum to 1.

OBJECTIVES

- Students will use a number line model to explore fractions.
- Students will understand the relationship between the visual representation of fractions and their symbolic forms.
- Students will add fractions with the same denominators.
- Students will develop strategies for finding two or more fractions that add up to 1.
