3D shapes are shapes with three dimensions — length, width, and height (or depth) — unlike flat shapes (like a square or circle) which have only two dimensions.
Key 3D shapes include: the cube, with six equal square faces, like an ice cube or a Rubik's cube. The sphere, perfectly round from every side, like a soccer ball. The cylinder, with two circular ends and a straight body, like a juice can. The cone, with a circular base and a pointed top, like an ice cream cone. And the pyramid, with a base and triangular faces meeting at one point.
Try searching your home together for objects that match each shape: can you find a can shaped like a cylinder? Or a ball shaped like a true sphere?
