A clear explanation is only part of a lesson. The next question is what the learner can understand and do with it. A copied example or a confident nod may leave that unanswered.
Before starting, choose a small task the learner should be able to complete afterwards. It might involve distinguishing a claim from its evidence, explaining a multiplication step or using an unfamiliar word appropriately. Make the goal clear enough for both of you to recognise progress.
Try a new example
After working together, change the details and ask the learner to proceed independently. Move from fractions represented by a cake to fractions represented by a length of ribbon. Examine a different advertisement after practising with the first. Listen to the explanation as well as checking the answer.
If the learner becomes stuck, investigate before repeating the whole lesson. Perhaps the question contains unfamiliar language, a prerequisite idea is missing or the first example encouraged a shortcut that does not generalise.
Use the response to make a teaching decision. Offer a different representation, revisit a smaller idea or provide another guided attempt. Check again with a fresh example when the support has changed.
Keep the assessment proportionate to its purpose. A brief conversation may be enough to plan tomorrow's work. A consequential qualification requires more substantial evidence and accountable assessment.
Record what was demonstrated, the support used and the next step. Over time, these observations provide a more useful account of progress than a list of sessions delivered. The lesson's conclusion becomes a starting point for the next explanation, rather than a final verdict on the learner.
