Documents, spreadsheets and presentations
Choose document, spreadsheet and presentation tools for their purpose.
Shared cross-level core and stretch unit. Start with the core questions, then use the stretch example for deeper work. The same unit is available in related class and board pathways; it is not a full grade-specific or examination-specification course. A teacher should select the appropriate depth and further topics.
Learn the idea
A document organises prose; a spreadsheet calculates from structured cells; a presentation supports an oral explanation. A formula must refer to the intended cells. Relative references move when copied; absolute references stay fixed. Formatting helps reading but does not make a calculation correct.
Worked example
If B2 contains quantity 4 and C2 unit price 25, =B2*C2 returns 100. Copying this formula down adjusts the row references. A fixed tax rate in F1 can be referenced as $F$1.
- Define the intended result.
- Write and inspect the formula.
- Test a normal, zero and boundary case.
Stretch example
A copied formula can silently use the wrong rate if a fixed reference was not locked. Data validation limits input; it cannot prove a plausible-looking value was entered correctly.
