Mastering Number – 2022/23

A national programme to secure firm foundations in the development of good number sense

This programme focuses on the key knowledge and understanding needed in Reception classes, and progression through KS1. Participating schools will receive central training (online and face to face) and a wealth of pupil-facing resources. 

There is an expectation that schools will provide a daily teaching session for all children 10 to 15 minutes, in addition to their normal maths lesson. Lead Teachers in schools will also contribute to an online community to share practice and engage in critical reflection. 

Who can take part?

Lead participants rom Work Group schools will be three teachers – one each from Reception, Year 1 and Year 2 – known as Lead Teachers.  Some support will also be given to subject leaders and headteachers. Where appropriate, Lead Teachers are expected to support the other teachers in their year group.

This programme and its Work Groups are open to all schools that have not yet engaged with the Mastering Number Programme. 


  • Your pupils will be able to clearly communicate their mathematical ideas
  • You will develop a secure understanding of how to build firm mathematical foundations
  • You will work to develop teaching strategies focused on developing fluency in calculation and number sense for all children
  • You will develop understanding and use of appropriate manipulatives to support your teaching of mathematical structures 

What is the cost?

The Mastering Number Programme is fully funded by the Maths Hubs Programme so is free to participating schools. Whilst digital rekenreks are freely available online, schools taking part in the September start cohort of this programme may wish to consider purchasing class sets of physical rekenreks for Year 1 and Year 2 prior to the start of the programme.
