Say the Relationship Before the Number
Describe how two values relate before calculating the difference between them.
Worked model: Say the Relationship Before the Number
- 1Describe how two values relate before calculating the difference between them
- 2Read again to mark quantities, units and relationships
- 3Represent the relationship with a sketch, table or equation
- 4Choose a method and check the result against the original question
For a recipe scaled from four to six people, say “multiply by one and a half” before calculating the new rice quantity. The relationship determines the number, rather than the learner guessing an operation.

Teacher language
Adapt these prompts to the task and your learners.
Our purpose is: Describe how two values relate before calculating the difference between them.
Show the relationship and explain the choice you made.
Try the new case on your own. Show the detail or reasoning that supports your answer.
Which support do you still need, and which part can you now do independently?
Across subjects
Science: quantities and units in a practical question. Humanities: extract relevant evidence from a dense prompt.
Adjust language support
Use a small word bank, visuals and partner rehearsal when needed. Extend with precise explanations and qualifications. Judge the support from the response to this task.
