2D and 3D Shapes

Exploring flat shapes and solid objects all around us!

What Are 2D and 3D Shapes?

Shapes are everywhere!
Some shapes are flat like drawings on paper - we call these 2D (two-dimensional) shapes. Other shapes are solid like toys or boxes - we call these 3D (three-dimensional) shapes. Let's learn to recognize them!

How to Tell Them Apart

1️⃣ 2D shapes are flat and have only length and width

2️⃣ 3D shapes are solid and have length, width, and height

3️⃣ You can hold 3D shapes, but 2D shapes are like pictures

Parent Tips 🌟

  • Shape Hunt: Go on a shape hunt around your house - find 2D shapes in pictures and 3D shapes in objects like cereal boxes or balls.
  • Play Dough Fun: Use play dough to create both 2D shapes (flatten them) and 3D shapes (build them up).
  • Building Blocks: When playing with blocks, name the 3D shapes you're using (cubes, rectangular prisms, cylinders).
