Overview:

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.

12 ) Explain why a fraction a/b is equivalent to a fraction nxa/nxb by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions. [4-NF1]

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.
Apply principles of fraction equivalence to recognize and generate equivalent fractions.
Example: a/b is equivalent to (n × a)/(n × b).
