Command word playbook
How to match each command word to the expected response style
Show formula, substitution, and unit; method marks need visible working.
Give reasons and link mechanism to outcome; each point needs a because/so chain.
Match the expected response style for “State” questions.
Match the expected response style for “Deduce” questions.
Match the expected response style for “Define” questions.
