What children learn in Level 70
- Solid shapes are not flat. You can hold them! This is a cube, like a number cube. It has 6 flat faces, and every face is a square.
- A rectangular prism is shaped like a box. It has 6 flat faces too, and they're rectangles.
- A cone has one flat face, a circle, and comes to a point, like an ice cream cone. It can roll!
- A cylinder has 2 flat circle faces, like a soup can. A sphere is round all over, like a ball, with no flat faces.
- Curved shapes can roll. Shapes with only flat faces slide or stack.
