Instructions

Play through this interactive game to learn about Comparing Two Fractions. Suitable for Grade 3, Grade 4, Grade 5.

Main Concepts

Fractions must refer to the same Whole to be compared, ex ½ of a 16in pizza is not the same as ½ of an 8in pizza.

Fractions with the same denominator are the same size.

Fractions with the same denominator but different numerators can be compared using the value of the numerators. ¼ < ¾ because ¾ has more unit fractions.

When referring to the same whole, the larger the denominator the smaller the unit portions will be.

Fractions with the same numerator can be compared by their denominators where the fraction with the smaller denominator is greater. Ex. 2/3 > 2/7

Discussion Questions

Before the Game

How can we tell which fraction is larger? How can we tell which fraction is smaller? What is the relationship between a whole pizza and a fraction of a pizza? When we split a pizza into equal parts, what is each part called? What does the denominator tell us about the fraction? What does the numerator tell us about the fraction?

After the Game

Which is smaller: ¾ or ¼ ? Which is larger: 2/3 or 3/3? How did the numerators and denominators of the customers' orders help you figure out how to serve them the correct amount? When can two fractions be compared and when can two fractions NOT be compared? When comparing two fractions, how can you tell which one represents the largest piece of cake? How do we compare two fractions with the same denominator?
