Command word playbook

How to match each command word to the expected response style

ExplainFrequency: 42

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

CalculateFrequency: 31

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

DescribeFrequency: 24

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

SuggestFrequency: 18

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

DeduceFrequency: 14

Match the expected response style for “Deduce” questions.

ConstructFrequency: 11

Match the expected response style for “Construct” questions.

StateFrequency: 22

Match the expected response style for “State” questions.
