Basics of Probability Part 1

Basics of Probability Part 1 is a Grade 7 probability investigation about predicting outcomes before an experiment is run. Students examine a spinner with equal sections and record predictions about how often different colors should occur. The important mathematical move is theoretical: students reason from the structure of the spinner rather than relying on trial results.

Use it in a small group when introducing theoretical probability and the idea of equally likely outcomes. Ask students to justify their predictions with fractions, ratios, or percentages instead of simply guessing.
