Lesson Plan - Get It!
Look at these two shapes:
They both have straight lines and lots of corners.
- So, how are they different?
One is 2D, and the other is 3D!
- Does your face look like this because you have no idea what 2D and 3D mean?
Don't worry! You're in the right place.
Learn about 2D and 3D shapes in this lesson, and practice finding different kinds of shapes all around you.
To learn what 2D and 3D mean, you first need to know what they stand for.
2D is short for two-dimensional, and 3D is short for three-dimensional. Two-dimensional and three-dimensional are ways to talk about different kinds of shapes.

2D vs. 3D Shapes! Mr. B's Brain - Ep. 2: 2D and 3D Shapes from Mr. B's Brain:
From that fun and silly video, you learned a lot!
You learned that 2D shapes are flat, and they go two ways. They only go up and down, and side to side. That's why they are called 2D!
You also learned that 3D shapes are solid, and they go three ways. They go up and down, side to side, and front to back. That's why they are called 3D!
- Where can you see 2D and 3D shapes in real life?
Look at these 2D and 3D shape examples in real life.
Now that you know how to tell 2D and 3D shapes apart, move on to the Got It? section to test your knowledge of shapes!
