Lesson details
Key learning points
- Compound shapes can be split into cubes and cuboids in different ways.
- Compound shapes can be split in different ways but the volume stays the same.
Keywords
Compound shape - A compound shape is a shape created with two or more basic shapes.
Strategy - A strategy is a planned approach used to solve a problem.
Common misconception
Pupils may default to trying to use the same strategy for every shape, for example, the 'partition and add' can be applied to most shapes although it might not be the most efficient.
Spend time exploring each strategy with basic dimensions for compound shapes at first. Explore different strategies for the same shape and encourage children to reason which strategy might be most efficient to use.
