Which shapes are 2D?

Let’s explore the world of shapes with Which Shapes are 2D? In this fun and interactive activity, you’ll identify and classify shapes as either 2D (flat) or 3D (solid), helping you understand the difference between the two.
 

You’ll strengthen your shape recognition and geometry skills by recognizing 2D shapes like squares, circles, and triangles, and learning about their properties such as sides and corners.
 

This activity boosts your spatial awareness and observation skills as you compare different shapes and identify whether they are flat (2D) or have depth (3D).
