Geometry and measurement: Maths

Angles and shapes links to the coding pathway: the turtle already turns through exterior angles, and classifying shapes is an algorithm students can write.

Foundations

Angles and shapesAngle facts, naming shapes, nets, transformations and algorithms.Angles at parallel lines, then angle sums, then naming shapes. Corresponding and alternate angles are equal and co-interior angles add to 180°; a triangle's angles add to 180°, and any polygon's to 180° for each triangle it splits into; triangles, quadrilaterals and polygons are classified by their sides and angles.Area, volume, circles and PythagorasArea, volume, circles, Pythagoras and time zones.Why the area formulas work (cut and move, halve and double), then area problems; volume as layers of the base; the parts of a circle, π, and the circumference; then Pythagoras' theorem for right-angled triangles; for Year 8, composite and irregular shapes, capacity and prism problems, the area of a circle, and time zones.After: Angles and shapes and Number Foundations and Algebra Foundations
