What you'll learn
- Design a short check around one explicit learning goal.
- Distinguish an incorrect answer from evidence about its possible cause.
- Plan feedback, a learner action and a follow-up check.
Begin with a goal you can observe
Choose what learners should be able to explain or do by the end of the activity. Then decide what response would show that understanding. A broad aim such as understanding fractions is difficult to check in one exchange. A narrower aim, such as explaining why fifths of the same whole can be compared by counting the shaded parts, gives both teacher and learner something concrete to discuss.
Original lesson plan: display two identical rectangles, each split into five equal parts. Shade two parts in one and four in the other. Ask learners to compare 2/5 and 4/5 and explain their choice. Success requires both the comparison and a reason about equal-sized parts.
Collect a response from every learner
A volunteer answer tells you about that volunteer. Plan a way to see other responses too, such as a short written explanation, a drawing or an individual answer card. Choose a response mode that is accessible to the learner. A correct selection alone may hide guessing, so a brief explanation or representation can be valuable evidence.
Ask each learner to draw the two fifths diagrams before discussing answers with a partner. Invite pointing or an oral explanation where writing would obscure the mathematical idea. Look at the representations before deciding whether to move on.
Interpret cautiously, then adapt
A wrong answer is a starting point for investigation. It does not by itself prove why the learner answered that way. Ask a focused follow-up and compare the explanation with the original response. If several learners show the same difficulty, a short whole-class example may be useful. A difficulty confined to one learner may call for a separate prompt while others extend the task.
A learner says 2/5 is greater than 4/5. Ask them to point to the amount in each drawing. They may have reversed the comparison sign, shaded unequal parts, or misunderstood the numerator. Each possibility calls for a different next step.
Make feedback usable
Feedback should help the learner improve the work. Specify an action they can carry out, allow time for it, and check what changes. The EEF guidance emphasises the principles of useful feedback rather than assuming that one delivery method is always best. In this example, a spoken prompt with a diagram may be more direct than a long written comment.
Instead of only writing incorrect, ask: use the same-sized rectangle for both fractions, shade the parts, then complete “4/5 is greater because…”. After the revision, use 1/6 and 5/6 as a fresh check. A copied correction on the first task is not enough evidence of independent understanding.
Separate learning checks from reporting decisions
A short check can inform teaching without becoming a formal grade. Summative assessment is used to summarise achievement at a point in time. The intended use of evidence matters: the same question can inform a teaching decision now and contribute to later reporting under a school policy. Do not assume that frequent testing is automatically formative; the evidence must lead to a useful response.
In your planning notes, record three items: what response you noticed, what you changed in teaching, and what the learner did on the follow-up. Avoid turning a temporary difficulty into a permanent ability label.
Take these ideas with you.
- Set a narrow goal and choose evidence that matches it.
- Investigate the reasoning behind an answer before choosing support.
- Give learners time to act on feedback and check again with a fresh task.
Check your understanding
Work out each answer before opening the explanation. These checks are not scored or saved.
All learners answer an exit question, but the teacher never looks at the responses. What is missing?
The evidence has not informed a teaching or learning decision. Read the responses, identify a specific need and plan a response, followed by another check.
A learner corrects an answer after copying the board. What would provide stronger evidence of understanding?
Ask the learner to solve a new example and explain the reasoning independently. Copying demonstrates completion of the correction, not necessarily understanding.
Plan feedback for a learner who compares equal fifths correctly but cannot explain why.
Ask them to label one fifth on both same-sized wholes, then describe how counting equal-sized parts supports the comparison. Check the explanation with a different pair of fifths.
