Add three addends

I can represent the addition of three addends.

Lesson details

Key learning points

  1. There can be three addends in an addition equation.
  2. We can represent this using a ten frame, a part-part-whole model or as an equation.

Common misconception

Children may struggle to make the connection between the concrete, pictorial and abstract representations.

When using the part–part–whole representation, make sure you explicitly connect each number with what it represents. Ask the children to describe what they can see using the full stem sentences. 'The ___ represents the __________.'

Keywords

  • Addends - Any numbers that are added together.

  • Represent - Showing something or standing for something.
