What is involved?
This programme focuses on the key knowledge and understanding needed in Reception classes, and progression through KS1. Lead teachers in participating schools will receive training and will be part of an online community, to share practice and engage in critical reflection.
Teaching materials will be provided for four short sessions each week, aimed at developing children's fluency and flexibility with number.
Who can take part?
Lead participants from 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.
What is the cost?
The Mastering Number Programme is fully funded by the Maths Hubs Programme so is free to participating schools.
