- Adjustable Spinner
A virtual spinner can be adjusted to have any number of sections of any size. It can then be spun any number of times in increments of 100,000.
- Box Model
The applet permits creating a box of up to 16 colored cubes including the possibility of duplicates. Cubes can then be drawn at random (with replacement). A bar graph shows the results that can be compared to the theoretical results.
- Coin Tossing (NLVM)
A single coin can be "tossed" any number of times. The results are shown in order, which can help with the concept of randomness. A bar graph shows results.
- Elementary probability
This site is considered a resource for elementary school teachers teaching probability in the elementary classroom. The site is organized by grade level with background information and lesson plan ideas for each grade listed.
- Experimental Probability (Shodor)
A spinner can be created with up to four regions or two number cubes can be made with each side adjustable from 1 to 6. The devices can then be used in experiments.
This site provides links to many lessons on probability. Includes lessons using spinners, dice, etc., and provides teachers with full lesson plan ideas to use in the classroom.
- Probability Resources (Math Forum)
Links to hundreds of articles, lessons, and applets related to probability.
