Key Stage 3

Access our free resources

You’ll find a wealth of classroom-ready resources that promote mathematical thinking, and other materials to support your teaching and your pupils’ learning in our collection of free resources.

Our resources are consistent with the DfE’s guidance on Teaching mathematics at Key Stage 3 (a summary of which is available from the NCETM) and complement the NCETM materials to help teachers develop a mastery approach in their classrooms and schools.

Key Stage 2-3 transition

MEI and our partners have developed a range of resources designed to help you to support students in their transition from primary learning.

Year 7 Get Calculating lesson plans

Our Year 7 Get Calculating lesson plans  focus on developing the use of calculators in a range of mathematical contexts. There’s a related series of lesson plans for Year 6.

I recently downloaded the MEI Deeper Maths trigonometry resources – I have a thing about trig! – and it’s absolutely super. Just love it

GeoGebra activities for Key Stage 3

MEI is investing its own charitable reserves to develop this collection of Key Stage 3 resources to support schools with maths education recovery and beyond.

Each unit includes a series of lessons comprising a GeoGebra activity for use during the lesson and a GeoGebra activity suitable for independent student learning. Each lesson also comes with a lesson plan detailing the planning behind each question in the activities, together with the answers.
