How do decomposing and recomposing shapes help us build our understand of mathematics?
Key Knowledge
An angle can be thought of as the result of a turning motion, a wedge, or two sides coming together to form a common vertex.
Key Skills
I can sketch, and determine the angle measure, of an angle created by turning a fractional amount of a right angle turn.
