Kate is an experienced senior leader who, in addition to her role with the London SW Maths Hub, is Mathematics Lead for GLF: a multi-academy trust of 27 schools, spanning across 4 counties. Prior to this, she successfully led mathematics at Nonsuch Primary School for 4 years, in addition to her role as Assistant Headteacher. Within these roles, she has supported many schools in improving mathematics teaching and learning. 
At Nonsuch, her impact in improving mathematics teaching and learning has been evident through the consistently high outcomes in mathematics – especially in 2016, when 100% of pupils in Key Stage 2 achieved Age Related Expectations as well as exceptional progress, and the school’s performance was ranked within the top 1% in the country. There has been a focus on high expectations for all children through a Teaching for Mastery approach.  
Kate is passionate about supporting teachers and schools to develop and embed Teaching for Mastery in mathematics pedagogy. She has excellent subject knowledge and is able to support schools to implement the approach coherently and strategically to ensure maximum impact.
Recent work includes:
  • Support to GLF schools to implement Teaching for Mastery

London SW Maths Hub Secondary Mastery Lead: Celeste Da Silva
Saint Cecilia's Church of England School
Article ImageCeleste da Silva is the secondary Teaching for Mastery (TfM) Lead for the South West London Maths Hub and the Mastery Lead at Saint Cecilia’s secondary school in South West London.  She has over 25 years of experience teaching maths, in London and internationally, across Key Stage 3 to Key Stage 5. She has used her excellent subject knowledge, gained from both her Mathematics degree and years of experience, to support teachers and mathematics departments with adopting a strategic and coherent approach to their mastery journey. 
After identifying a gap in provision at Saint Cecilia’s she was appointed Numeracy Co-ordinator to support low-attaining pupils.  She subsequently developed a numeracy programme for Key Stage 3 pupils which was tailored to the pupils’ individual needs and provided a holistic, personalised intervention. She uses visual representations to expose the mathematical structures that develop pupils’ conceptual understanding and encourages them to make connections.  Regular tracking of data has been used effectively in order to measure impact. This has also required her to train other colleagues to be able to deliver the programme whilst maintaining a strategic overview.
In 2015 Celeste participated in NCETM’s Secondary England-China exchange working with maths teachers in Shanghai and then hosted two teachers from China for a week in 2016.  It was this experience that prompted greater thought about how to teach maths which contributed to her developing her understanding of TfM.  As a direct result of Celeste’s experience on the exchange she now works with the South West London Maths Hub providing TfM professional development on mathematics teaching and learning to both primary and secondary teachers as well as PGCE students; support includes working strategically on mathematics pedagogy, lesson design approaches and collaborative planning.
Celeste is a passionate advocate of ‘mastery in mathematics’, the fundamental concept being the belief all pupils can engage with, understand and succeed at maths given the supportive strategies and nurturing approaches encouraged by TFM programme; maximising maths enjoyment while minimising maths anxiety.
Recent work includes:
  • Support to secondary teachers with TfM pedagogy and lesson design in their classroom
  • Support to mastery specialists to implement TfM in their department
  • Delivering CPD to secondary teachers across South West London in support of the TfM approach
  • Developing and delivering training to NQT’s and PGCE students.
  • Developing and delivery numeracy training to non-specialist teachers and teaching assistants
