Sorting maths ideas

An AR classroom game for Grade 6. Learners can aim with their hands at the camera or play by tapping the screen.

This set has 4 rounds in an interactive sorting activity.

Sample questions

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

  1. Sort the equations into groups.

    Sort into

    • solved by subtracting
    • solved by dividing
    • x + 4 = 9
    • 3x = 12
    • x + 7 = 15
    • 5x = 20
    Read the explanation

    Solve an equation by undoing what was done to the variable.

  2. Sort the numbers into groups.

    Sort into

    • perfect square
    • not
    • 25
    • 20
    • 49
    • 30
    Read the explanation

    A perfect square is a number whose square root is exact.

  3. Sort the statistics into groups.

    Sort into

    • average
    • measure of spread
    • mean
    • range
    • median
    • the largest value take away the smallest
    Read the explanation

    An average says where the centre is; a measure of spread says how far apart the values are.

Before you play

Game teaching guide

What children will practise

Sort equations by how they are solved (subtract or divide), perfect squares, averages versus spread, and ratio versus percentage problems, linking to writing ratios in ค 1.1 ป.6/2.

What's in the worksheet

4 sorting rounds, dragging 4 cards into 2 groups - Solved by subtracting or dividing: x + 4 = 9, 3x = 12, x + 7 = 15, 5x = 20 - Perfect square or not: 25, 20, 49, 30 - Average or spread: mean, range, median, largest minus smallest - Ratio or percentage: shared 2 : 3, 20% off, water to syrup 4 : 1, 85 out of 100

How to use it in class

Use as a mid-term review; about 5 minutes. - Play in teams; in round 1, have teams say the opposite of what was done to x - If range and median have not been taught, introduce them briefly with the class's scores before round 3 - In round 4, point out that : signals a ratio, while % or 'out of 100' signals a percentage - Some items extend beyond primary indicators. Use them for discussion or preparation for Grade 7, not to judge attainment - Play it linked to the class to record results in the mark book.

Common sticking points

- Round 4: '85 out of 100' may go under ratio, since it also compares two amounts - Round 3: 'largest minus smallest' is the definition of range; children may not realise the two cards are the same thing - Round 2: 20 may be put with the perfect squares because it is a round number

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