Sample questions

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

  1. Sort the numbers into groups.

    Sort into

    • less than 7
    • more than 7
    • 3
    • 9
    • 5
    • 10
    Read the explanation

    Compare each with seven - whatever you reach before seven is less.

  2. Sort the sums into groups.

    Sort into

    • makes 5
    • does not make 5
    • 2 + 3
    • 3 + 3
    • 4 + 1
    • 2 + 2
    Read the explanation

    Work out each answer first, then see whether it makes five.

  3. Sort the things into groups.

    Sort into

    • comes as a pair
    • just one
    • shoes
    • a nose
    • socks

Game teaching guide

What children will practise

Sort numbers by comparing them with 7, find additions that make 5, tell even from odd numbers, and sort things that come in twos from things that come singly.

What's in the worksheet

4 rounds, a sorting game with 4 items each - 3 and 5 are less than 7; 9 and 10 are greater - 2 + 3 and 4 + 1 make 5; 3 + 3 and 2 + 2 do not - Shoes and socks come in twos; nose and mouth come singly - 4 and 10 are even; 9 and 3 are odd

How to use it in class

Use to review comparing numbers and adding within 10. About 6 minutes. - Play as a class; for round 4, children pair up counters to see whether one is left over - For round 2, say each sum's answer aloud before dragging - If many miss round 1, ask "Counting from 1 to this number, have we passed 7 yet?" - Play it linked to a class and the scores go into the class gradebook.

Common sticking points

- In round 4, calling 9 even or 10 odd before the pairing idea is secure; pair up real counters - In round 3, hesitating over the nose because it has two nostrils; say the game counts the nose as one - In round 2, putting 3 + 3 under makes 5 after a counting-on slip

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