### Math Simulations

- The Stock Market Game - (4-12) This World Wide Web (WWW) site is designed to help students in grades 4 to 12 understand the stock market, the costs and benefits involved in decision making, and the sources and uses of capital and other related economic concepts
- Simulations Lesson Plans
- Simulation lessons
- Topology and Geometry Software
- Calculus - (11-12) This site contains interactive java applets that demonstrate concepts from calculus. The page has three main sections that cover topics concerning limits, derivatives, and integrals.
- The megapenny project - (5-8) This site aims to help visitors understand and appreciate the magnitude of large numbers by showing and describing arrangements of large quantities of U.S. pennies.
- Math and physics applets (9-12) This site contains java applets that are designed to help students visualize important concepts in mathematics and physics. Applets include simulations and demonstrations of sound waves, membrane oscillators, and vector fields.
- The learning equation - (9-12) This site presents 15 applets for exploring mathematics topics in geometry, trigonometry, and probability. Each applet has detailed directions for use and suggestions for exploration.
- Powers of ten - (6-12) This site features a series of pictures from nature that each have a wider or narrower field of view by a power of ten. The initial picture is a one meter by one meter view of a flower bed.
- Educational Java programs - (K-10). This site, started in November 1997, provides Java applets with lesson activities that can be used as online tools to help and enhance the education of children both at school and at home.
- Virtual laboratories in probability and statistics - (11-12) This site provides a set of web based resources for students and teachers of probability and statistics. The site is divided into chapters grouped into topics for probability, statistics and special models, including Bernoulli Trials.
- VESTAC, Visualization of and Experimentation with STAtistical Concepts - (11-12) This site features applets designed to help students more easily visualize and understand abstract statistics concepts through interactive computer-aided instruction.
- Seeing statistics - (10-12) This site was designed to help students of statistics learn the dynamic, visual nature of statistical concepts using interactive methods. The site uses more than 150 Java applets.
- Visual fractions - (4-9) This site aims to reduce fraction anxiety, called Fractionitis, in adults and students by helping the user picture fractions and the operations that can be performed on them. There are instructions and problems to work through.
- Explore Math - (8-12) This site features interactive activities designed to help students visualize and explore a spectrum of major mathematical concepts from elementary algebra through pre-calculus.
- Vectors - (8-12) This) site features static sketches with mathematical explanations and interactive vector models that are intended as supplementary material to help students in their first encounter with vectors.
- Population growth and balance - (5-10) This site gives students the opportunity to use a mathematical model to conduct simulation population dynamics experiments.
