Comparing Sums of Unit Fractions

Illustrative MathematicsVaries

The purpose of this task is to help develop students' understanding of addition of fractions; it is intended as an instructional task. Notice that students are not asked to find the sum because in grade 4, students are limited to computing sums of fractions with like denominators (i.e. fractions where 1 denominator is a multiple of the other). Rather, they need to apply a firm understanding of unit fractions (fractions with one in the numerator) and reason about their relative size.
