Fair Game Design Worksheet

Worksheet illustration

📊 Part 1: Quick checks & probability

1. Which word best describes a situation where every outcome has the same chance?

Certain

Impossible

Equally likely

Likely

2. Check all statements that show a game is fair:

Each player starts with the same number of counters

One player gets extra turns every round

Chance tools (dice/spinner) are balanced or equally likely

One player always begins on a winning square

3. A fair six-sided die is used. Show your working: what is the probability of rolling a 4?
4. A spinner has three sectors: 50%, 30% and 20%. Which choice best describes this spinner?

Fair — all outcomes are equally likely

Unfair — some outcomes are more likely than others

Cannot tell without playing

✏️ Part 2: Peer review, refinement & reflection

5. When your group played this game, did any player have a clear advantage? Use chance language (certain, impossible, likely, unlikely, equally likely) to explain.
6. Suggest one specific change to make the game fairer (rule, dice/spinner change, starting position, etc.). Explain briefly why this helps.
7. Challenge: A player wins if they roll a 6 on a fair die. Show your working: what is the probability they win in one roll? What is the probability they win if they may roll twice (stop if a 6 appears)?
8. After making your change, write one sentence using chance vocabulary to explain why the updated game is fair. Then sketch the change (rule or board) below.
