This Probability Tools app also includes:
- Join to access all included materials
You call it, heads or tails? Whether you just need one coin to toss or something more interesting, such as multiple dice or a spinner to use, this app provides a number of interesting tools.
The app Probability Tools contains three different tools to use in investigating chance events, or for general classroom use.
- Coin toss
There are a number of different adjustments one can make to the dice and spinner tools. The coin toss tool has fewer adjustments and only one coin.
- Single coin only
- Touch coin to toss
- Tally of heads and tails recorded
- Select number of dice (1 to 6 dice possible)
- Select value of each face
- Numbers 1 to 6 possible
- Can set dice to have the same number on multiple faces
- After a role, the tally of the values on each die is kept
- Select number of sections
- 2 to 6 sections possible
- Each section is a different color
- Select the number of degrees for each section (The sum must equal 360 degrees.)
- Change the direction of the spin to the left or right
- Tally of the results kept
- Custom spin is possible (You input a number of degrees to move the spinner)
Use these tools to conduct different experimental probability studies. Compare theoretical and experimental probability. Middle schoolers can explore a number of beginning probability activities. For example, after many rolls, create a two-dice frequency chart, graph results in a bar graph have them explain their results.
More advanced probability learners can make connections between geometry and differences in sector sizes on a spinner or investigate how changing the number of dice or numbers on the dice effect probability.
- This tool makes running multiple experiments possible in a short period of time. The app keeps the tally for you, allowing users to concentrate on the outcomes.
- The spinner and dice toss have a number of useful customizations
- Customization of the tools is retained between uses (Can't save different customized settings)
- There is only one coin in the coin toss tool
