Teaching Effective Early Mathematical Understanding in Primary Schools (TEEMUP) is a professional development programmeA programme is a package of support, including professional development, that helps early years educators to improve particular areas of practice and children’s outcomes. for reception and year 1 teachers focused on early maths and self-regulationHow children monitor their emotions and thoughts, and adapt their behaviour in different circumstances.. The programme is designed to equip teachers with the tools to tailor their teaching to their school’s context and resources, rather than offering a scripted set of activities.

TEEMUP aims to develop teachers’ content knowledge, pedagogical knowledge, and pedagogical content knowledge, while also supporting improvements in their confidence and self-assessment in teaching maths. Coaching is designed to help teachers apply and adapt their maths curriculum across reception and year 1 in ways that strengthen children’s mathematical development and address their wider needs, such as self-regulationHow children monitor their emotions and thoughts, and adapt their behaviour in different circumstances..

Developed and delivered by a team at the University of Oxford, the programme includes training sessions, coaching, and access to a dedicated website with resources and additional materials. Reception and Year 1 teachers received training together, to support collaboration on their approach to maths teaching, with the aim of delivering a smoother transition for children between reception and Year 1.
