Sample questions

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

  1. Match each fraction to its simplest form.

    • 2/4
    • 3/9
    • 4/16
    • 6/8
    Read the explanation

    Divide top and bottom by their highest common factor.

  2. Match each division to its answer.

    • 72 ÷ 9
    • 45 ÷ 5
    • 42 ÷ 7
    • 35 ÷ 7
    Read the explanation

    Dividing by a single digit.

  3. Match each sequence to its rule.

    • 2, 4, 6, 8
    • 5, 10, 15, 20
    • 2, 4, 8, 16
    • 100, 90, 80
    Read the explanation

    Look at the difference between the numbers.

Game teaching guide

What children will practise

Simplify fractions to lowest terms, match divisions to quotients, state the rule of a number pattern, and list all factors of numbers up to 12.

What's in the worksheet

4 matching questions - 2/4 = 1/2, 3/9 = 1/3, 4/16 = 1/4, 6/8 = 3/4 - 72 ÷ 9 = 8, 45 ÷ 5 = 9, 42 ÷ 7 = 6 - 2, 4, 6, 8 adds 2 each time; 2, 4, 8, 16 multiplies by 2 - 12 has factors 1, 2, 3, 4, 6, 12 and 7 has factors 1, 7

How to use it in class

Use after teaching lowest terms, 6-7 minutes, team mode. - 2, 4, 6, 8 and 2, 4, 8, 16 start the same; have teams check the third and fourth numbers - For factors, start with 7, which has the fewest, and mention that 7 is prime - After the fractions question, ask whether 3/4 can be simplified further - Play it linked to the class to record results in the mark book

Common sticking points

- Matching 6/8 with 1/2 or 1/4 because of the 8. Divide top and bottom by 2 - Matching 2, 4, 8, 16 with "add 2" by looking only at 2 to 4 - With incomplete factor lists, pairing 1, 2, 5, 10 with 12. Test dividing by 5

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