SAFMEDS-GwE (Say All Fast Minute Every Day Shuffled) is a project to improve pupils basic mathematics fluency skills using an evidence-based teaching strategy.

The project is a cluster-randomised controlled trial to evaluate the effect of a precision teaching intervention called SAFMEDS (Say All Fast Minute Every Day Shuffled) on the numeracy attainment of pupils in GwE primary schools. SAFMEDS is a teaching intervention that has already been used successfully to improve the numeracy skills of pupils in smaller scale studies in schools in North Wales.
