Lesson 28 Classify 3D shapes

3D Shapes

Moving into Unit 10 we will be discussing shapes and how we describe a shape.

By the end of this unit, we will classify and sort 2 and 3 dimensional shapes based on attributes.​

3D Shape Vocabulary

A geometric figure that has length, width, and height.

​

​Solid Figure

The flat surface or bottom of solid figures.

Base

Face

The place were two faces meet.

Edge

A corner where three or more edges meet.

Vertex
