Lesson: Adding Parts of a Whole Mathematics • 4th Grade

In this lesson, we will learn how to use models to add fractions with the same denominator where the sum is one at most.

Lesson Plan

Students will be able to

  • use concrete and pictorial representations to add two fractions with the same denominator within one whole,
  • recognize that only the numerator changes when fractions with the same denominator are added (the number of equal parts in the whole stays the same),
  • write and complete addition sentences,
  • apply knowledge of adding parts of a whole when solving word problems.
