Words to know
- Spreadsheets and Data Models:
- Use formulas, references, tables, charts, and scenarios to solve practical problems.
- model:
- A rule or representation used to describe a situation and make a prediction.

- • Keep every number, symbol, label, and unit in its correct place.
- • Show enough working to check how you reached your answer.
Helpful habits
- • Read the whole question before choosing what to do.
- • Show one clear step at a time and check each step.
- • If you are stuck, draw a model, try smaller numbers, or revisit the example.
