Command word playbook

How to match each command word to the expected response style

ExplainFrequency: 28

Give reasons and link mechanism to outcome; each point needs a because/so chain.

DescribeFrequency: 18

State features in sequence or list observable properties — do not explain causes unless asked.

StateFrequency: 22

Match the expected response style for “State” questions.

CalculateFrequency: 11

Show formula, substitution, and unit; method marks need visible working.

SuggestFrequency: 8

Apply knowledge to an unfamiliar context; concise, practical points score best.
