Sample questions

A few real prompts from the game to help you choose an activity for your class.

  1. Which fraction is greater than 2/3?

    • 3/4
    • 1/3
    • 1/2
    Read the explanation

    Three quarters is more than two thirds - over twelfths it is nine against eight.

  2. Which fraction equals 2/4?

    • 1/4
    • 1/2
    • 2/8
    Read the explanation

    Divide top and bottom by two and you get one half.

  3. Which fraction is the smallest?

    • 1/3
    • 1/6
    • 1/9
    Read the explanation

    The tops match; the bigger the bottom, the smaller the fraction.

Game teaching guide

What children will practise

Compare fractions, simplify to lowest terms, find equal fractions, and spot an improper fraction greater than 1 (indicator ค 1.1 ป.4/4).

What's in the worksheet

6 multiple-choice questions - Which fraction is greater than 2/3? 3/4 - 2/4 equals 1/2, and 3/6 simplifies to 1/2 - Smallest of 1/3, 1/6, 1/9: 1/9 - Which fraction is greater than 1? 5/4 - 4/8 and 1/2 are the same

How to use it in class

Use after teaching equivalent fractions and lowest terms, 6-8 minutes, team mode, with fraction strips for every team. - Q2, Q4 and Q6 all come back to 1/2; afterwards, ask pupils for more fractions equal to 1/2 - For "greater than 2/3", the denominators 3 and 4 are not multiples of each other, so compare with fraction strips rather than calculating - Play it linked to the class to record results in the mark book

Common sticking points

- For 4/8 versus 1/2, choosing "4/8 is greater" because its numbers are bigger. Lay fraction strips side by side - For "greater than 2/3", many have no method to compare 3/4 with 2/3 and guess. Use fraction strips - Choosing 2/8 as equal to 2/4 by changing only the bottom. Stress that top and bottom must be multiplied or divided by the same number

Play together first, then build on it with a worksheet for the same level.
