Lesson details
Key learning points
- A representation helps to make sense of an equation or problem.
- A bar model can be used to help solve additive problems.
- A part-whole model can be used to identify the equation needed to solve an additive problem.
Keywords
Represent - To represent something means to show something in a different way.
Common misconception
Pupils struggle to find a way into solving the number puzzles at first.
It is important that pupils can identify what the whole is for each problem. Encourage pupils to draw a bar model to help link the problem to its part and wholes. This may help them identify the parts and whole and how to calculate any missing parts.
