Lesson details

Key learning points

  1. When both addends are equal, we are doubling.
  2. Doubling means adding two equal addends.
  3. Doubling a whole number always gives an even number.

Common misconception

Children may struggle to see that a double is two of the same thing.

Spend time exploring doubles that can be found in the children's immediate environment e.g. using their hands or playing a game of dominoes.

Keywords

  • Double / doubling - To become twice as many.

  • Addends - Any of the numbers that are added together.
