Mastering Number

Mastering Number at Reception and KS1
Supporting pupils to develop good number sense


Booking closed for 2024/25. Express an interest for 2025/26
A national programme now in its third year, offers schools that have not previously been involved in Mastering Number the opportunity to secure firm foundations in the development of good number sense for all children from Reception through to Year 1 and Year 2. The aim over time is that children will leave KS1 with fluency in calculation and a confidence and flexibility with number. Attention will be given to key knowledge and understanding needed in Reception classes, and progression through KS1 to support success in the future.

Mastering Number Embedding the Impact Community
Support for schools that have already engaged in Mastering Number
This community is open to all 2023/24 Mastering Number at Reception and KS1 schools and Mastering Number at Reception and KS1 schools from previous cohorts that have not yet participated in this community. All participating schools need to be engaged in a 2024/25 Teaching for Mastery Work Group (or have a formal EOI in working with the hub on teaching for mastery in future years).
One nominated Lead Teacher will receive support to make Mastering Number a permanent element of the school curriculum. The Lead Teacher will engage in an online learning community and have continued access to all teaching materials, recording of central sessions, and sample teaching videos.

Mastering Number at KS2
Secure firm foundations in multiplicative relationships
Knowledge of multiplication and division and its applications forms the single most important aspect of the KS2 curriculum, and is the gateway to success at secondary school. This project enables pupils in Years 4 and 5 to develop fluency in multiplication and division facts, and a confidence and flexibility with number that exemplifies good number sense.
Professional development materials will be provided to cover five short sessions a week, with participants expected to support colleagues in their year groups to use the resources with all Year 4 and 5 classes.
