Instructions

Play through this interactive game to learn about Visual Models of Equivalent Fractions. Suitable for Grade 3, Grade 4, Grade 5.

Main Concepts

Understand that the numerical process of multiplying the numerator and denominator of a fraction by the same number, n, corresponds physically to partitioning each unit fraction piece into n smaller equal pieces. A whole is then partitioned into n times as many pieces, and there are n times as many smaller unit fraction pieces as in the original fraction (Multiplying ½ by 2/2 is the same as splitting a rectangle with 2 equal parts into 4 equal parts with 2 parts shaded in to show that ½ = 2/4.)

Multiplying a fraction by any fraction with the same numerator and denominator is the same as multiplying by 1 which is why the value does not change.

Find equivalent fractions by multiplying by a fraction equivalent to 1 in the form of n/n, represent this with models getting addition partitions without shading in addition unit fractions.

Discussion Questions

Before the Game

What does the numerator of a fraction tell us? What does the denominator of a fraction tell us? How can we compare fractions with different denominators?

After the Game

Does the value of a fraction change when you multiply it by one? What is the value of a fraction with the same numerator and denominator? What is a method that can prove if two fractions are equivalent?
