Independent learning and metacognition

The ‘What do I understand?’ page is common to all worksheets. Learners are encouraged to develop independent learning skills and can use their reflection as a guide for revision. The feedback will also help you to identify areas where a whole class needs attention.


The teacher guidance provides model answers for each worksheet, plus guidance on learners’ common misconceptions. Learners can use the model answers to self- or peer assess.
