Sample questions

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

  1. Put the powers in order from smallest to largest.

    • 2^2
    • 2^4
    • 3^2
    • 5^2
    Read the explanation

    Work out each value first, then put them in order.

  2. Put the probabilities in order from smallest to largest.

    • 1
    • 1/2
    • 1/3
    • 1/6
    Read the explanation

    Convert them to decimals before comparing.

  3. Put the numbers in order from smallest to largest.

    • 0
    • -1
    • -10
    • 5
    Read the explanation

    Negatives come first, then zero, then positives.

Game teaching guide

What children will practise

Order powers by value, order probabilities from 1/6 up to 1, order numbers including negatives, and put the steps for finding a probability in order.

What's in the worksheet

4 ordering rounds of 4 cards - Powers smallest first: 2^2, 3^2, 2^4, 5^2 - Probabilities smallest first: 1/6, 1/3, 1/2, 1 - Numbers smallest first: -10, -1, 0, 5 - Steps for a probability: count all outcomes, count wanted outcomes, write a fraction, simplify

How to use it in class

Use as enrichment after introducing powers and probability; about 4-5 minutes. - Play in teams; in round 1 have teams write the values under the cards first: 4, 9, 16, 25 - In round 2, draw a 0 to 1 probability line on the board and place the cards - In round 4, if a team counts wanted outcomes first, discuss that the answer is the same - Play it linked to the class to record results in the mark book.

Common sticking points

- Round 1: 2^4 put before 3^2 by looking only at the base, or by thinking 2^4 is 8 - Round 3: -10 and -1 swapped because 10 is bigger than 1 - Round 2: 1/6 and 1/3 swapped because 6 is bigger than 3 - Round 4: the first two steps can be swapped, so children who swap lose marks

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