**TOPIC**: Probability

**TITLE**: Spinners

**SOURCE**: National Library of Virtual Manipulatives

**DESCRIPTION**: Virtual spinner. Spinner can have up to 11 equal-sized regions. Each region has a different colour and can also be allocated a name or number. Thus spinner acts as a random generator. The relative size of each region can be changed, simulating sampling of events with different probabilities. It is possible to select a number of spins up to 999, and graph the results.

**SUGGESTED USE**: VELS Level 5, Chance and Data, Introduction to experimental probability. Can use to compare experimental probability with theoretical probability. Individual student use.

**TOPIC**: Probability

**TITLE**: Adjustable Spinner

**SOURCE**: National Council of Teachers of Mathematics

**DESCRIPTION**: Virtual spinner. User can select up to 12 regions of different colours, and can select the size of each region expressed as a percent. It is possible to select a number of spins up to 100,000. The results are given as a table comparing theoretical probability with experimental. These can also be compared as pie charts. Note: this spinner offers more flexibility than spinner described above.

**TITLE**: Box Model

**SOURCE**: National Library of Virtual Manipulatives

(A given number can be put in more than once, thereby changing the theoretical probabilities.) The user can also select how many times numbers are drawn. The experimental and theoretical probabilities are displayed on a graph. The user can see the order in which numbers were drawn, and therefore can see how often runs of a particular number occur.

**SUGGESTED USE**: VELS Level 5, Chance and Data, Introduction to experimental probability, Individual student use.

**TOPIC**: Probability

**TITLE**: Fire

**SOURCE**: National Council of Teachers of Mathematics

**DESCRIPTION**: Shows a grid of trees in a forest. User selects a tree at which to start a fire. User also selects probability that fire will spread to adjacent trees. The results show which parts of the forest are burned down, and what proportion is burned. If the probability that fire will spread to an adjacent tree is 0.33 or less, the fire tends to die out quickly. At probabilities 0.67 or higher, most of the forest tends to be burned down. The fire is more likely to die out if fire is started in a corner due to the lower number of adjacent trees. This applet illustrates how a relatively small change in the probability of the fire spreading can have a significant effect on the overall result, because the fire is able to spread to up to four adjacent trees. It also shows how the same starting event with same probability can produce a massive difference, depending on whether the fire takes hold or not.

**SUGGESTED USE**: VELS Level 5, Chance and Data, Individual students use. Students could try this activity a number of times for different starting position (middle and corner) and different probabilities, so that they can see effect of changing these parameters.

**TITLE**: Coin Tossing

**SOURCE**: National Library of Virtual Manipulatives

**DESCRIPTION**: Simulates the tossing of a coin. User can choose the number of times coin is tossed. The results include number of heads and tails tossed, and a bar graph of the proportion of heads and tails. Also shows the longest run of heads and longest run of tails. Alternatively user can select the longest run of heads, and see how many tosses are required to produce this run. It is possible to change the probability of heads. Thus, for example user can make heads an unlikely event and find out how many tosses it takes to get a certain number of heads in a row.

**SUGGESTED USE**: VELS Level 5, Chance and Data, Introduction to experimental probability, Individual student use. It would be useful to devise associated activities. For example students can toss coin say 20 times and repeat this a number of times to see the distribution of heads. Can also be used to see how often runs of heads or tails occur (more often than students expect).
