Grades 3-560-75 minSource: Creative Dad Company

Kids design their own carnival-style probability game, run dozens of trials to check whether it's actually fair, and adjust the odds until it is. It's a playful way to make abstract probability concepts concrete and immediately testable.

Setup

Place common or recycled supplies for Game-Show Probability Studio on one work surface and choose a safe area for the test. Read the four activity directions aloud; drawings, paper models, and household substitutes may replace specialized materials, and no digital tool is required.

Activity

  1. Design a game using dice, cards, or a spinner and predict how often a player should win if the game is fair.
  2. Build the finished game board and rules, setting the odds based on the prediction.
  3. Test the game with at least 20 trials, tallying the actual results, then adjust the game's odds when the real win rate doesn't match the fair prediction.
  4. Run the finished game as a class carnival booth and share the trial data proving how fair it really is.

Done when: The group produces the Game-Show Probability Studio solution, completes the described test, makes the revision called for by the evidence, and supports its final explanation with an observed or measured result.

Materials

dice, a blank spinner game kit, cards, small prizes or tokens, poster board for the game board, markers
