The 'Orchestrating Numeracy and the Executive' (The 'ONE') programme bridges educators’ needs and recent evidence, to train early years practitioners to support early numeracy and executive functions together. Results from that study suggest that children who took part in the programme made more progress in numeracy skills and some executive function skills than children who did not take part in the programme. The lead investigators are Gaia Scerif (University of Oxford), Emma Blakey (University of Sheffield) and Victoria Simms (Ulster University). In particular, we aim to give children experiencing economic disadvantage more evidence-based opportunities to develop their early numeracy skills.' We look forward to working with in many settings and understanding what works for early numeracy learning!'
