📚 Topic Summary
Flat shapes, also known as 2D shapes, are shapes that you can draw on a piece of paper. Examples include circles, squares, triangles, and rectangles. Solid shapes, also called 3D shapes, have thickness and take up space. Think of a ball (sphere), a box (cube or rectangular prism), or a cone like an ice cream cone! Learning to identify these shapes is a key building block for understanding geometry.
