#### Description:

In this activity, students highlight portions of circles or squares that are equivalent to a given fraction. This activity allows students to explore equivalent fractions by making it necessary that each of the three fractions have a different denominator but have the fractions be equal. This activity includes supplemental materials, including background information about the topics covered, a description of how to use the application, and exploration questions for use with the java applet.

#### CCSS.Math.Content.3.NF.A.1: Common Core State Standards for Mathematics

Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.

#### CCSS.Math.Content.3.NF.A.3a: Common Core State Standards for Mathematics

Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line.

#### CCSS.Math.Content.3.NF.A.3b: Common Core State Standards for Mathematics

Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3). Explain why the fractions are equivalent, e.g., by using a visual fraction model.

#### CCSS.Math.Content.5.NF.A.1: Common Core State Standards for Mathematics

Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators.
