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.
Name or point to the specific feature asked for — avoid extra explanation.
State features in sequence or list observable properties — do not explain causes unless asked.
Match the expected response style for “Draw” questions.
Present multiple perspectives with evidence; balance breadth and depth.
Match the expected response style for “Deduce” questions.
