Grade 3 · Data & Probability
Likelihood of Simulated Events
Grade 3 probability introduces simulation: using coins, dice, and spinners to model chance events. The gap between theory (a fair coin lands heads half the time) and experiment (flip it 10 times and count) is one of the most important ideas in all of probability. Results will vary: that is what randomness means. But over many trials, experimental results approach theoretical predictions. This law of large numbers is discoverable by Grade 3 students through hands-on experimentation.

WHAT STUDENTS WILL LEARN
✓Use comparative probability language: certain, uncertain, more likely, less likely, equally likely
✓Understand that some events are based on chance: coin flips, dice rolls, spinners
✓Conduct and record simple probability experiments
✓Compare predicted outcomes to actual experimental results
✓Connect to the Snowsnake game and other First Peoples games of chance
