Command word playbook

How to match each command word to the expected response style

DescribeFrequency: 14

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

ExplainFrequency: 10

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

StateFrequency: 8

Match the expected response style for “State” questions.

WriteFrequency: 6

Match the expected response style for “Write” questions.

IdentifyFrequency: 7

Name or point to the specific feature asked for — avoid extra explanation.

CalculateFrequency: 2

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

DrawFrequency: 3

Match the expected response style for “Draw” questions.
