# Teaching 4.NF.B.3.d – Solve Word Problems Involving Addition and Subtraction of Fractions

## Number & Operations – Fractions – 4th Grade

**Build fractions from unit fractions.**

CCSS.Math.Content.4.NF.B.3.d

Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators, e.g., by using visual fraction models and equations to represent the problem.

**Teacher Notes**

Teaching students the strategies to solve word problems is aided by the use of graphic organizers. Students need to be comfortable using visual fraction models to add and subtract fractions in context.
