Double It

Overview

Children explore what happens when numbers are doubled using objects.

Learning Objective
Children understand doubling as adding the same number again.

Resources needed

  • Small objects (stones, sticks, counters)

Lesson stages

0 / 7 done

  3. 3 Add the same number again.
  4. 4 Count all objects together.
  5. 5 Repeat with different numbers.
  6. 6 Ask children to explain what doubling means.
  7. 7 Compare results and look for patterns.

Variations

  • Use fingers to show doubles

  • Challenge children with larger numbers
More information

Use the word 'double' alongside the phrase 'the same again'. Reinforce with physical mirroring.

Pair children so one group makes the first set and the other copies it.

Do children understand doubling as a process, or do they just count all objects? Can they predict double before counting?

Use identical natural objects (stones, seeds). Fingers are a powerful free tool — show a number on one hand, then mirror it on the other.

Children frequently confuse doubling with adding 2. Stress that doubling means adding the same number again — not just any addition. Use the phrase 'the same again' consistently.
