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