Unit 3, Lesson 3# Add fractions with unlike units using the strategy of creating equivalent fractions.

EngageNY 60 min(s)

In this lesson, begin adding fractions with unlike denominators. They model the addition of unit fractions by folding papers and then drawing a model. For example, students solve 1/2 + 1/4. Then they add a unit fraction and non-unit fraction by drawing and writing models. Finally, students add two non-unit fractions.
