Lesson Planning

Day 1 Teaching
Show a variety of 3-D shapes. Write the words: face, edge, vertex (plural: vertices) and polyhedron on the board. Revise their meanings and ask children to use these words to describe one of the shapes to a partner. Discuss the properties of different shapes, using these terms.

Group Activities
-- Make and describe 3-D shapes, identifying faces, edges and vertices.
-- Make 3-D models using cubes.

Day 2 Teaching
Show children a selection of 3-D shapes. Explain that we will sort these into prisms and pyramids and those which are neither. Identify the properties of prisms and those of pyramids and ensure children understand that there are different examples of each. Sort using other headings/criteria.
Group Activities
-- Use the in-depth problem-solving investigation ‘Soma Cube’ as today’s group activity.
Or, use these activities:
-- Make, describe and classify 3-D shapes.
