Mathematics

Parallel sides, powers of 2, percent

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

    • has parallel sides
    • no parallel sides
    • rectangle
    • triangle
    • trapezium
    • circle
    Read the explanation

    Count the pairs of parallel sides in each shape.

  2. Sort the numbers into groups.

    Sort into

    • a power of 2
    • not
    • 8
    • 12
    • 16
    • 20
    Read the explanation

    A number whose only prime factor is two is a power of two.

  3. Sort the sums into groups.

    Sort into

    • a percentage problem
    • a fraction problem
    • 20% off
    • 1/4 eaten
    • scored 80%
    • 2/3 left
    Read the explanation

    Separate the percentage problems from the fraction problems.

Game teaching guide

What children will practise

Sort shapes with and without parallel sides (linked to parallel lines in ค 2.2 ป.5/1), numbers that are powers of 2, percentage versus fraction problems, and units of angle versus time.

What's in the worksheet

4 sorting rounds, dragging 4 cards into 2 groups - Has parallel sides or not: rectangle, triangle, trapezium, circle - A power of 2 or not: 8, 12, 16, 20 - Percentage or fraction problem: 20% off, 1/4 eaten, scored 80%, 2/3 left - Measures angle or time: degree, minute, right angle, hour

How to use it in class

Use to close the parallel lines and quadrilaterals unit or as an end-of-term review; about 4 minutes. - Play on the projector as a class; for round 1 have children hold two rulers parallel to show parallel sides - If round 2 goes badly, write 2, 4, 8, 16, 32 by doubling on the board and replay - In round 4, note that in this game minute means time - 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 2: 12 and 20 may go in the powers-of-2 group because they are even; keep doubling to see whether 12 or 20 appears - Round 1: the trapezium may go in the no-parallel group because its sides slope; one pair of parallel sides is enough - Round 4: right angle is the name of an angle, not a unit, so some children will hesitate over it

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