Resources for schools covering different subjects including Science, PE, and Maths.
e.g. The healthy eating toolkit features separate toolkits for KS1 and KS2. Developed by teachers, the resources are linked to the curriculum and also feature cross-curricula ideas. The resources are flexible so you can choose how to fit them into your timetable and tailor activities to suit your class.
