Shapes and objects: Year 7 – planning tool
This planning resource for Year 7 is for the topic of Shapes and objects. Students build on their knowledge of two-dimensional shapes. They classify triangles according to their side length (scalene, isosceles, equilateral) and their angle properties (right, acute, obtuse). Students identify and describe different quadrilaterals (square, rectangle, parallelogram, rhombus, trapezium and kite) in terms of their side length, parallel edges and equal angles. Students also investigate the angle sum of a triangle and quadrilateral.

In this sequence of 10 lessons, students prove angle sum rules, classify quadrilaterals, draw 3D views in 2D, and apply volume and geometric reasoning to problems.

Making triangles
Students study the concept of triangle inequality, which determines if three positive numbers can serve as the side lengths of a triangle. This principle states that a triangle is possible if the largest of the three numbers is smaller than the sum of the other two. To explore this, students experiment with various combinations of three natural numbers.
