Discovering Shapes: Exploring 2D & 3D

What do you already know about 2D and 3D shapes?

Learning Objective

At the end of the lesson you will be able to name, describe, and classify 2D shapes and 3D objects, and spot them in your classroom and the world around you.

What Do We Already Know?

Share with your partner: What 2D or 3D shapes can you name? Where have you seen them before?

Getting Hands-On: Feely Bag Game

Use your sense of touch to explore shapes without looking. Can you feel the number of sides, faces, or corners? Try to guess the shape using its properties.

Identifying 2D Shapes in 3D Objects

Look for squares, rectangles, triangles, and circles as faces on 3D objects. Can you find more examples?

Cuboid: All faces are rectangles or squares. Cylinder: Base is a circle. Pyramid: Faces include triangles and squares.

3D Object

Shape Hunt: I Spy with My Little Eye

Explore your classroom to find as many 2D and 3D shapes as you can. Describe their properties using words like sides, faces, edges, and vertices.

Classifying and Grouping Shapes

Sort shapes by the number of sides, faces, or vertices. Can you name triangles, quadrilaterals, pentagons, and hexagons? Try grouping 3D shapes: cubes, spheres, cylinders, pyramids.

Mathematical Language for Shapes

2D Shape Terms

Side, corner (vertex), angle, edge.

Face, edge, vertex, base.

Tiling Patterns in the Environment

Find examples of tiling, like floor tiles or brick patterns. Use two different shapes to design your own tiling pattern.
