2. The Nature of Mathematics

2A. Patterns and Relationships
• 3-5: 2A/E2. Mathematical ideas can be represented concretely, graphically, or symbolically.

9. The Mathematical World

9C. Shapes
• 3-5: 9C/E1. Length can be thought of as unit lengths joined together, area as a collection of unit squares, and volume as a set of unit cubes.
• 6-8: 9C/M7. For regularly shaped objects, relationships exist between the linear dimensions, surface area, and volume.
• 9-12: 9C/H2. When the linear dimensions of an object change by some factor, its area and volume change disproportionately: area in proportion to the square of the factor and volume in proportion to its cube. Properties of an object that depend on its area or volume also change disproportionately.
