Talk about it
Mark doesn't just say the game is rigged — he collects data to prove it. Good arguments rest on evidence, not just a hunch.
- What evidence did Mark gather to back up his claim?
- Why is 'I have proof' stronger than 'I think so'?
- How could you test whether a game is really fair?
Quick work-a-long
Vocabulary: evidence, claim, proof, data.
Try it: Make a claim about a coin flip (like 'it lands heads half the time'). Flip 20 times and record the data. Did it match?
