Sample questions

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

  1. Sort the numbers into groups.

    Sort into

    • decimal
    • fraction
    • 0.5
    • 1/2
    • 2.75
    • 3/4
    Read the explanation

    A decimal has a point; a fraction has a line.

  2. Sort the numbers into groups.

    Sort into

    • less than 1
    • more than 1
    • 0.3
    • 1.8
    • 2/5
    • 5/2
    Read the explanation

    Compare with one: a decimal with no whole number in front, and a proper fraction, are both less than one.

  3. Sort the sums into groups.

    Sort into

    • divides exactly
    • leaves a remainder
    • 20 ÷ 4
    • 21 ÷ 4
    • 36 ÷ 6
    • 37 ÷ 6
    Read the explanation

    Separate the divisions that come out exactly from those with a remainder.

Before you play

Game teaching guide

What children will practise

Tell decimals from fractions by how they are written (indicator ค 1.1 ป.4/5), compare decimals and fractions with 1, sort exact divisions from those with a remainder, and three-digit from four-digit numbers.

What's in the worksheet

4 sorting questions with 2 boxes each - 0.5 and 2.75 are decimals; 1/2 and 3/4 are fractions - 0.3 and 2/5 are less than 1; 1.8 and 5/2 are more - 20 ÷ 4 and 36 ÷ 6 divide exactly; 21 ÷ 4 and 37 ÷ 6 leave a remainder - 456 and 999 have three digits; 1234 and 5000 have four

How to use it in class

Use as decimals are introduced, 5-6 minutes, team mode. - Q2 includes 5/2, an improper fraction; have teams draw 5 half-circles to see it is more than one whole - After Q1, notice that 0.5 and 1/2 are the same value even though they sit in different boxes - Q3 and Q4 are quick basic review - Play it linked to the class to record results in the mark book

Common sticking points

- Putting 5/2 under less than 1, used to fractions below one. Compare the top and bottom numbers - Hesitating over 0.3 and 2/5 because they are in different forms. Ask what a 0 before the point means - Putting 999 under four digits because it is close to 1000

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