What children learn in Level 82
- A box is a solid shape called a rectangular prism. Its flat sides are called faces. The front face is colored.
- Unfold the box, and you can see all 6 faces at once. Each face is a rectangle, a quadrilateral!
- A cube is a box with every edge the same length. All 6 of its faces are squares.
- Cylinders and cones have round faces, so none of their faces are quadrilaterals.
Georgia's K-12 Mathematics Standards:
- 3.GSR.6.2 — Classify, compare, and contrast polygons, with a focus on quadrilaterals, based on properties. Analyze specific 3-dimensional figures to identify and describe quadrilaterals as faces of these figures.
