1.3.4 - Scalars and vectors

Understand scalar and vector quantities and know examples of each type of quantity and recognise vector notation.

Use - scalars and vectors to connect the rule to the data and decision in the question.

This matters because - scalars and vectors determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - scalars and vectors to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Scalars and vectors is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
