Data & Probability

Chance Simulator

Spin spinners, roll dice, flip coins, draw marbles — run 1 to 1000 trials and watch results converge toward expected probability.

Why this tool helps: Students think past results affect future odds. Running hundreds of trials makes the law of large numbers visible.

Year levels: Year 3, Year 4, Year 5, Year 6, Year 7, Year 8 Curriculum: Australian Curriculum aligned
