13. Using area and length fraction models, explain why one fraction is equivalent to another, taking into account that the number and size of the parts differ even though the two fractions themselves are the same size.

a. Apply principles of fraction equivalence to recognize and generate equivalent fractions.

Example: ^a/_b is equivalent to ^{(n x a)}/_{(n× b)}.

In this interactive activity, students will be led through steps to reduce fractions to their simplest form by generating an equivalent fraction. There are teaching activities as well as practice activities available. A handout with practice problems can be printed. After utilizing this resource, the students can complete the short quiz to assess their understanding.

This video from Cyberchase features Bianca working on her aunt and uncle’s farm. Bianca is excited because she’s getting a new pet. She uses equivalent fractions to combine different lengths of wood to build a roof on a house for the new pet. In the accompanying classroom activity, students use equivalent fractions to solve a problem and create word problems of their own.
