An AR classroom game for Grade 5. 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 shapes into groups.

    Sort into

    • straight edges only
    • has a curved edge
    • pentagon
    • circle
    • hexagon
    • oval
    Read the explanation

    Shapes with a curved edge, and shapes with only straight ones.

  2. Sort the numbers into groups.

    Sort into

    • divides exactly by 6
    • does not divide exactly by 6
    • 12
    • 14
    • 30
    • 20
    Read the explanation

    A number divides by six exactly only if it divides by both two and three.

  3. Sort the formulas into groups.

    Sort into

    • finds area
    • finds perimeter
    • width × length
    • (width + length) × 2
    • side × side
    • side × 4
    Read the explanation

    Area formulas and perimeter formulas give answers in different units.

Before you play

Game teaching guide

What children will practise

Sort several kinds of maths knowledge: straight-sided versus curved shapes, numbers that divide exactly by 6, area versus perimeter formulas for rectangles and squares, and mixed numbers below or above 2.

What's in the worksheet

4 sorting rounds, dragging 4 cards into 2 groups - Straight edges only or a curved edge: pentagon, circle, hexagon, oval - Divides exactly by 6 or not: 12, 14, 30, 20 - Finds area or perimeter: width × length, (width + length) × 2, side × side, side × 4 - Less or more than 2: 1 1/2, 2 1/4, 1 3/4, 3 1/2

How to use it in class

Use as a review before the perimeter and area unit or as a lesson closer; about 4-5 minutes. - Solo mode works since each round is short, but let pairs talk before round 3 - If round 2 goes badly, explain that 6 = 2 × 3, so the number must be even and divide by 3, then test 14 and 20 - For round 3, have children draw a rectangle, shade the inside (area) and trace the edge (perimeter) - Play it linked to the class to record results in the mark book.

Common sticking points

- Round 2: 14 or 20 may go in the divides-by-6 group because they are even; point out they must also divide by 3 (1 + 4 = 5, 2 + 0 = 2) - Round 3: side × side and side × 4 get confused because both say side; ask whether the side is multiplied by itself or four sides are added - Round 4: 1 3/4 may be put above 2 because of the 3 and 4; look at the whole number first

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