WHAT HAPPENS in Biased Bingo?

In this unit, students devise bingo cards which they believe will give them the best chance of winning a game of addition fact bingo.

Students will:

• Familiarise themselves with the game of bingo. (Discover)
• Use their understanding about addition facts to identify which numbers will not occur (according to the game鈥檚 rules). (Discover, Devise)
• Record the frequency with which the other numbers are expected to appear. (Devise)
• Construct a bingo card which they feel has the greatest likelihood of winning a game. (Develop)
• Test and reflect upon their decisions. (Defend)

Learning goals

• Conducting repeated probability experiments or games, identifying the outcomes, and describing differences between them using probability vocabulary.
• Exploring probability beyond coin tossing and dice rolling.
• Exploring a probability experiment where the theoretical probability of a certain outcome can be calculated.
• Make predictions based on data collected.
• Identify all possible outcomes of an event.
• Assign probabilities to simple events using fractions (1/2, 1/6, etc).

Resources

• Photocopy masters are within the 听
• A set of 30 standard 4×4 Bingo cards (rather than the suggested 5×5) can be found
