Lesson Details
Key learning points
- The properties must match the shape you have created.
- Lines are not perpendicular when they are not at right angles to each other.
- Lines are not parallel because they are not always the same distance apart.
Common misconception
Pupils may find it challenging to recognise that the properties of composed shapes may be different from the shapes they are composed of.
Drawing around compound shapes can really support children thinking about this as a 'new' shape with new properties.
Keywords
