Clock Arithmetic (Activity)
Work with various types of clocks in order to learn about modular arithmetic operations. Parameters: Number of hours on the clock.
Outlines the approach to playing the chaos game and how it relates to geometric fractals.
This worksheet is for use with the Comparison Estimator activity (http://www.shodor.org/interactivate/activities/ComparisonEstimator/).
Students learn basic ideas about graphing points on the coordinate plane.
Spinner (Activity)
Create a game spinner with one to twelve sectors in order to look at experimental and theoretical probabilities. Parameters: Number of sectors, number of trials.
Advanced Monty Hall (Activity)
Choose one of N doors to experimentally determine the odds of winning the grand prize behind one of the doors, as in the TV program "Let's Make a Deal." Parameters: Number of doors, number of trials, staying or switching between the two remaining doors.
Normal Distribution (Activity)
Change the standard deviation of an automatically generated normal distribution to create a new histogram. Observe how well the histogram fits the curve, and how areas under the curve correspond to the number of trials. Parameters: standard deviation, number of trials, class intervals.
Adjustable Spinner (Activity)
Create a game spinner with variable sized sectors to look at experimental and theoretical probabilities. Parameters: Sizes of sectors, number of sectors, number of trials.
This worksheet is for use with the Life activity (http://www.shodor.org/interactivate/activities/Life/).
Crazy Choices Game (Activity)
Compare theoretical and experimental probabilities, using dice, cards, spinners, or coin tosses. Three different probabilities can be compared at once. Parameters: Type of probabilities, number of trials.
