CCSS.Math.Content.7.SP.C.7 - Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy.
CCSS.Math.Content.7.SP.C.7.a - Develop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events. For example, if a student is selected at random from a class, find the probability that Jane will be selected and the probability that a girl will be selected.
CCSS.Math.Content.7.SP.C.7.b - Develop a probability model (which may not be uniform) by observing frequencies in data generated from a chance process. For example, find the approximate probability that a spinning penny will land heads up or that a tossed paper cup will land open-end down. Do the outcomes for the spinning penny appear to be equally likely based on the observed frequencies?

- Adjustable Spinner - Students can create a game spinner with variable sized sectors to look at experimental and theoretical probabilities.
- Adjustable Spinner - Change the number of sectors and increase or decrease their size to create any type of spinner. Then, conduct a probability experiment by spinning the spinner many times. How does the experimental probability compare with the theoretical probability
- Analyzing game probabilities - Multiple-choice quiz [5 problems]
- Coin Flipping page - Flip up to 100 coins and see the total number of heads and tails. Excellent for teaching about probability.

- Lions and Tigers - Predict the likelihood of a simple event (rolling a die) as a fraction
- Marbles - Students learn about sampling with and without replacement by modeling drawing marbles from a bag. Parameters: Number and color of marbles in the bag, replacement rule.
- Probability - Five question multiple-choice quiz from Glencoe Math
- Probability Theory: The Layman's Guide to Probability - An in-depth but easily readable guide on probability theory, covering various aspects of the theory with a bias to gambling games and strategies. Includes working examples in an excel spreadsheet.
- Two Colors - Students choose between three boxes and choose one marble from the box to look at conditional probabilities.
- Understanding Experimental Probability - Experiment with experimental probability using a fixed size section spinner, a variable section spinner, 2 regular 6-sided number cubes or design your own number cubes.
- What are Your Chances - What many people refer to as 'good luck' can actually be explained by a little knowledge about probability and statistics. This dice game allows you to see how increasing or decreasing the number of dice rolls effects an outcome.
