3D Shapes

March 11, 2023

Scheme of work: GCSE Foundation: Year 9: Term 2: 3D Shapes

Prerequisite Knowledge

Draw 2-D shapes and make 3-D shapes using modelling materials; recognise 3-D shapes in different orientations and describe them
recognise angles as a property of shape or a description of a turn
compare and classify geometric shapes, including quadrilaterals and triangles, based on their properties and sizes
identify acute and obtuse angles and compare and order angles up to two right angles by size
identify lines of symmetry in 2-D shapes presented in different orientations

Success Criteria

Use conventional terms and notations: points, lines, vertices, edges, planes, parallel lines, perpendicular lines, right angles, polygons and regular polygons.
rotation symmetries; use the standard conventions for labelling and referring to the sides and angles of triangles; draw diagrams from written description
identify properties of the faces, surfaces, edges and vertices of: cubes, cuboids, prisms, cylinders, pyramids, cones and spheres
construct and interpret plans and elevations of 3D shapes.

Key Concepts

Understanding and applying the keywords is essential throughout this topic.
Students need to understand the geometrical difference between a prism and pyramid.
Horizontal lines are not drawn on isometric paper.

Common Misconceptions

Students often get confused about which elevation to draw and how to include hidden detail.
Some students find it very difficult to draw 3D shapes on isometric paper.
