    Multiplication Mountain

    Year 1 Multiplication

    Make equal groups, count in 2s, 5s and 10s, and discover doubling — the first steps towards times tables.

    • Ages 5–7
    • 3 quests

    Multiplication starts long before times tables. In Year 1, children make equal groups, count in 2s, 5s and 10s, and discover doubling — the ideas that times tables are built on.

    What your child will learn

    • Recognise and make equal groups of objects
    • Count in steps of 2, 5 and 10
    • Find the total of several equal groups
    • Double numbers up to 10

    Equal groups

    "3 groups of 2" is the Year 1 way of saying 3 × 2. Multiplication Mountain shows the groups as pictures so children can see why counting in 2s — 2, 4, 6 — gives the same answer as counting every object.

    Counting in steps

    Counting in 2s, 5s and 10s is a skill that pays off for years. Pairs of socks, fingers on hands and stacks of ten coins are all great real-life examples.

    Example questions

    Here are a few questions like the ones in the first quest. Can you solve them?

    1. 1. True or false? 5 groups of 2 make 10.

      Show answer

      Answer: True. Count in 2s, 5 times: 2, 4, 6, 8, 10. So 5 groups of 2 make 10.

    2. 2. How many are there in 4 groups of 2?

      • 18
      • 12
      • 9
      • 8
      Show answer

      Answer: 8. Count in 2s, 4 times: 2, 4, 6, 8. So 4 groups of 2 make 8.

    3. 3. How many are there in 2 groups of 2?

      • 3
      • 4
      • 2
      • 7
      Show answer

      Answer: 4. Count in 2s, 2 times: 2, 4. So 2 groups of 2 make 4.

    Tips for grown-ups

    • Count pairs of shoes in 2s and fingers in 5s.
    • Chant counting patterns while climbing stairs or clapping.
    • Double small numbers with a mirror: 3 buttons and their reflection make 6.
