2D shapes are flat. 3D shapes are solid. Some examples of 3D shapes are cubes, spheres, and cones.

## LET’S BREAK IT DOWN!

### Properties of flat shapes

A circle has no sides and no corners. A triangle has three sides and three corners. A rectangle has four sides and four square corners. A square is a rectangle where all of the sides are the same length.

### Balls are spheres.

A sphere is a solid shape with no sides and no corners. A baseball is a sphere. A basketball is a sphere.

### Boxes are rectangular prisms.

You see a box. All the faces of the box are shaped like rectangles. This box is a 3D shape called a rectangular prism. A cube has 6 faces that are squares.

### A bucket is a cylinder.

You have a bucket of ice cream. The bucket has a circle at the top and at the bottom. The sides of the bucket are curved. This is a cylinder. A can of soda is also a cylinder.

### Ice cream cones are cones.

We scoop the ice-cream into an ice cream cone. A cone is a 3D shape that has a circle on one end. The other end is pointy. The orange markers on roads are called traffic cones. This is because they are shaped like cones.
