PhET Simulation: Estimation
written by the Physics Education Technology Project
Available Languages: English, Spanish
This applet allows the user to explore size estimation in one, two and three dimensions. Multiple levels of difficulty allow for progressive skill improvement. Teaching ideas and activities are included. The direct link to the simulation is given as a mirror URL.

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.
