## Lesson: Plane Shapes and Solid Shapes

Introducing the Concept

Provide children with a number of experiences in which they can practice using and identifying plane and solid shapes. Begin by having children match shapes, first by type and then by size. Encourage them to use the names of both plane and solid shapes in their conversation and class discussion. Have children practice holding, looking at, and then describing shapes by their attributes. Provide enough experiences so that children feel comfortable with simple plane and solid shapes and their attributes.

**Materials:** two sets of cut-out plane shapes (Worksheet 1 (PDF file), Worksheet 2 (PDF file)) for each child; objects such as a small rubber ball, an eraser in the shape of a rectangular prism, a cube-shaped box, a can, a party hat, a pyramid

**Preparation:** Copy Worksheet 1 (PDF file) and cut out the shapes for each student. Make a copy of Worksheet 2 (PDF file) for each child. Gather examples of solid shapes as listed above.

**Prerequisite Skills and Concepts:** Children should be familiar with the names of solid and plane shapes.
