Explain the Wrong Turn
Present an incorrect solution and ask learners to explain the thinking that may have produced it.
Worked model: Explain the Wrong Turn
- 1Present an incorrect solution and ask learners to explain the thinking that may have produced it
- 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
Show a solution that multiplies only the numerator when making an equivalent fraction. Locate the wrong turn, explain how it changes the value, and repair the step by applying the same factor to numerator and denominator.

Teacher language
Adapt these prompts to the task and your learners.
Our purpose is: Present an incorrect solution and ask learners to explain the thinking that may have produced it.
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.
