Available Languages: English, Spanish

This interactive Flash animation allows students to explore size estimation in one, two and three dimensions. Multiple levels of difficulty allow for progressive skill improvement. In the simplest level, users estimate the number of small line segments that can fit into a larger line segment. Intermediate and advanced levels offer feature games that explore area of rectangles and circles, and volume of spheres and cubes. Related lesson plans and student guides are available for middle school and high school classroom instruction.

This is part of a larger collection developed by the Physics Education Technology project (PhET).

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.
