L.O.-To deduce missing angles of shapes.
Achieve – I can identify the relevant expected total of the inner angles for common shapes.
Challenge - I can calculate missing angles for common shapes when provided the other relevant angles.
Aspire – I can explain how to blend the technique for solving multi-step missing angles with multiple linked shapes.
Maths/Numeracy lesson for KS2, year 4, 5 or 6 depending on how you aim it. Plenty of differentiation through various tasks. Recap angles in right angles, straight lines and full turns. Building on understanding of total angles in quadrilaterals and triangles. Using the corners of the shapes to make a straight line or full turn to help reinforce why they add up to 180 or 360. Deducing missing angles. Combining multiple shapes.
