Sample questions

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

  1. Match each sum to its answer.

    • -5 + 3
    • -4 - 3
    • 6 - 9
    • -2 + 8
    Read the explanation

    Common calculations with negative numbers.

  2. Match each fraction multiplication to its answer.

    • 1/2 × 1/2
    • 1/3 × 1/2
    • 2/3 × 1/2
    • 2/5 × 1/2
    Read the explanation

    Multiply top by top and bottom by bottom, then simplify.

  3. Match each formula to what it finds.

    • distance ÷ time
    • speed × time
    • total ÷ count
    • largest - smallest
    Read the explanation

    Knowing what each formula finds is what lets you pick the right one.

Before you play

Game teaching guide

What children will practise

Add and subtract negative integers, multiply fractions by 1/2, match formulas to what they find (speed, distance, mean, range), and match numbers to their square roots.

What's in the worksheet

4 matching rounds of 4 pairs each - Negative integers: -5 + 3 with -2, -4 - 3 with -7, 6 - 9 with -3, -2 + 8 with 6 - Fraction products: 1/3 × 1/2 with 1/6, 2/3 × 1/2 with 1/3 - Formula to what it finds: distance ÷ time with speed, total ÷ count with mean - Square roots: 36 with 6, 64 with 8

How to use it in class

Use as a slightly beyond-syllabus review for a class heading to ม.1; about 5 minutes. - Play in teams with a number line on the board for round 1 - In round 3, have teams say each formula as a sentence, e.g. speed is distance divided by time - If round 2 goes badly, point out that multiplying by 1/2 means halving - Play it linked to the class to record results in the mark book.

Common sticking points

- Round 1: -4 - 3 worked out as -1, then wrongly paired with -2 or -3 - Round 3: distance ÷ time and speed × time swapped because both mention time - Round 2: 1/3 × 1/2 and 2/3 × 1/2 get swapped by children who look only at the denominators; multiply the tops too

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