Sample questions

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

  1. Sort the data by the kind of graph that suits it.

    Sort into

    • bar chart
    • pie chart
    • the number of students in each class
    • which colours children prefer
    • daily sales
    • how a day is divided between activities
    Read the explanation

    A bar chart compares amounts; a pie chart shows parts of a whole.

  2. Sort the numbers into groups.

    Sort into

    • divides exactly by 4
    • does not divide exactly by 4
    • 16
    • 18
    • 36
    • 22
    Read the explanation

    A number divides by four exactly when its last two digits do.

  3. Sort the numbers into groups.

    Sort into

    • less than 1,000
    • more than 1,000
    • 876
    • 1,240
    • 999
    • 3,050
    Read the explanation

    Compare with a thousand - anything with four digits or more is greater.

Before you play

Game teaching guide

What children will practise

Choose a suitable kind of chart for some data, with review of dividing by 4, comparing numbers with 1,000, and telling units of length from units of area.

What's in the worksheet

4 sorting questions with 2 boxes each - Students in each class and daily sales suit a bar chart; which colours children prefer and how a day is divided suit a pie chart - 16 and 36 divide exactly by 4; 18 and 22 do not - 876 and 999 are less than 1,000; 1,240 and 3,050 are more - Metre and centimetre are units of length; square metre and square centimetre are units of area

How to use it in class

This set contains no chart to read. Use it as a light 5-minute review before a bar chart lesson, team mode. - For Q1, have an example bar chart and pie chart ready to project, since P4 pupils have not learned pie charts - For area units, draw a 1 cm square on paper to show how it differs from 1 cm - Play it linked to the class to record results in the mark book

Common sticking points

- Putting "which colours children prefer" under bar chart, which is also valid. Hear the reasoning and explain that "proportion" in the Thai wording points to a pie chart - Putting square metre under length because it contains "metre". Underline "square" - Putting 18 under "divides by 4" because it is even

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