About this app

Probability is an interactive elementary math game about describing and comparing the chance of drawing a red ball from a bag. Adjust the numbers of red and blue balls to see the chance expressed in words and as a number, then compare two bags by their red-ball share rather than by raw counts. Four missions and a challenge quiz reinforce impossible, unlikely, even, likely, and certain events.

Use cases

  • Elementary students learning basic probability
  • Teachers demonstrating fractions, ratios, and chance
  • Families practicing probability vocabulary together
  • Learners comparing proportions through visual examples

Features

  • Adjustable red and blue ball counts in a bag
  • Chance shown with words and a numerical value
  • Side-by-side comparison of two bags
  • Four guided missions for building target probabilities
  • Quiz with word-based and bag-comparison questions
  • Score, streak, and star tracking
