- Possible outcomes for more than two events can be listed.
- Possible outcomes for more than two events can be systematically listed.
Common misconception
Pupils want to avoid writing lists of outcomes.
Always model and bring explicit attention to a systematic list. The benefits of working systematically is the likelihood of error is reduced.
Keywords
Systematic - When listing outcomes systematically, they are listed in such a way as to ensure all outcomes are recorded.
As pupils are listing outcomes try to encourage them to think about how many they end up with and why. This will help with the product rule for counting in the future.
