Grade 2 · Math · Lesson 26

Recognize 3D Objects

Unlike 2D shapes, 3D objects have length, width, and height — they take up space. We describe them using faces (flat surfaces), edges (where two faces meet), and vertices (corners). Some 3D shapes also have curved surfaces.

What this lesson teaches

1Name the six common 3D solid shapes
2Decide whether a 3D shape has only flat faces or at least one curved surface
3Give a real-life example of each 3D shape
