In anticipation of that, we've brought together a collection of lesson ideas designed to help you to consolidate understanding and extend thinking through enquiry in a variety of topic areas.

As usual, we've got the generous and talented members of the TES Maths community to thank for these imaginative ideas. So take a look and be inspired to try something different with your classes.
