Find out more about the Yorkshire and the Humber Maths Hub leadership team:
Kathryn Greenhalgh - Senior Leadership Link
Having been involved with Maths Hubs since their inception in 2014 as the Yorkshire and the Humber Maths Hub Lead (then co-leading with Charlotte), I fully endorse all it stands for. I was lucky enough to participate in the first ever China / England Teacher Exchange and seeing how the pupils were taught over there, how the teachers were professionally developed and how impactful this was for ALL pupils really galvanised my belief that 'every child can' in mathematics - we just have to teach them in a way that enables that to happen.
In my role as Senior Leadership Link, I bring the years of experience I have in System Leadership as Maths Hub Lead and the strategic knowledge and expertise from my previous role as Executive Director of Mathematics for Outwood Grange Academies Trust. I have also chaired the National Maths Hub Council for eight years, an absolute privilege, which has afforded me great insight into how, as a national collaborative network of Maths Hubs and Local Leaders of Maths Education, we can work together to improve outcomes for ALL pupils in maths in England.
I demonstrate my commitment by continuing to work as an Intensive Support Partner and as a facilitator of the high quality professional development the Maths Hub delivers.
Charlotte Thornton - Maths Hub Lead
I have been involved with Yorkshire and the Humber Maths Hub since 2015 and co-led the Hub from 2019 before becoming the sole Maths Hub lead in 2024. As part of my role, I oversee the planning, monitoring, and evaluation of all Hub activities. I direct the team, ensuring alignment with the Maths Hub's national goals whilst striving to meet the local maths needs in our region. I collaborate closely with the NCETM to drive continuous improvement and success. Additonally, I work as a School Standards and Improvement Partner for Maths for Outwood Grange Academies Trust and feel that it's important for my Maths Hub Lead role to still experience the classroom. Prior to that, I was Head of Maths at an outstanding Catholic School in Lancashire.
As a learner of maths myself, I could only be really good at it if I knew where the maths came from. My own learning experience meant that as a teacher I was always passionate about giving the students 'the why' behind the maths to really develop their understanding. Back in 2015, I attended a Shanghai Open Classroom event in the middle of Hull, in a school with 70% disdavantage and high EAL. When I saw these Year 4 students articulating their understanding of fractions so beautifully and with such enthusiasm - it was then that I knew that the Maths Hubs was for me and how it was aligned with my own philosophy!
Holly Myers - Maths Hub Manager
I joined Yorkshire and the Humber Maths Hub in 2019 as an administrator and have held several roles with the hub during that time. As Maths Hub Manager I lead on the operational processes and activity of the Hub, working closely with the leadership and administrative teams. I work collaboratively with other Operational Managers nationally and represent a group of hubs as part of an advisory working group.
I am passionate about the Maths Hubs Programme and enjoy being part of a team that makes a difference for children.
Megan Bailey - Assistant Maths Hub Lead for Secondary
As the Assistant Maths Hub Lead for Secondary, I am responsible for ensuring the smooth and effective delivery of the Hub’s secondary programmes. I work closely with our team of Secondary Local Leaders of Maths Education, supporting them to lead high-quality professional development and the successful implementation of change across schools in the region.
I strongly believe that continually developing specialist knowledge for the teaching of mathematics—and collaborating with others to do so—is essential for effective teaching and learning and for securing positive outcomes for all students. It is an honour to work alongside such passionate practitioners and to see the impact of this work in classrooms.
Rose Dalders - Assistant Maths Hub Lead for Secondary and Targeted Support
My work involves leading Work Groups, supporting Local Leaders of Maths Education in the facilitation of their Work Groups and leading Targeted Support in secondary schools. Alongside this, I am a Secondary School Standards and Improvement Partner for Outwood Grange Academies Trust, where I have the privilege of still being in the classroom day to day. Before joining Outwood and Maths Hub, I was Head of Maths in an outstanding school in Bradford.
I strongly believe that the single most impactful thing on a child's education is quality first teaching in the classroom. I am passionate about equity and believe that a child's postcode should not determine the quality of education that they receive. Strong professional development is essential to ensure that teachers are equipped to teach for understanding, and that is why the work that we do is so valuable.
Vanessa Beaumont - Assistant Maths Hub Lead for Secondary
As the Assistant Maths Hub Lead for Secondary, I am dedicated to transforming the way students experience mathematics. I lead Work Groups and mentor Mastery Specialists, supporting schools and colleagues at all levels to foster excellence in the classroom.
I believe every student deserves to experience the "why" behind the maths, moving beyond rote procedural memorisation toward deep, relational understanding. My mission is to ensure access to high-quality education that sparks genuine curiosity rather than a reliance on memorised methods.
I am a firm believer that empowering teachers is the key to student success. By providing high-quality professional development that builds teacher knowledge and confidence, we can create a lasting, positive impact on pupil outcomes.
Christine Robinson - Assistant Maths Hub Lead for Post 16
My work involves overseeing the Maths Hub Level 3 programmes (A Level Pedagogy and A Level Core Maths) as well as the Level 2 Cross Phase Work Group. The latter supports students who are either sitting Foundation tier maths (pre or post 16), or Functional Skills qualifications.
I also support colleagues who are undergoing professional development as part of the Post-16 GCSE/FSQ Mastery Specialist programme.
While the complexity of the mathematics involved is completely different, I believe that it is the ideas behind Teaching for Mastery that is having the biggest impact on student understanding and confidence at all levels. The deeper understanding comes from having the tools to break down problems, draw on representations and make connections.
Sarah Young - Assistant Maths Hub Lead for Primary and SEND Equity Lead
Throughout my career, I have been passionate about exploring how to help close the attainment gap and teach in a way which sparks a genuine love for the subject.
While much of my teaching experience has been based in the Primary classroom, my professional work has since transitioned into the Secondary phase. This cross-phase perspective has deepened my commitment to the transformative power of a "Can Do" school culture and the importance of curriculum continuity and cohesion.
My journey with the Hub began as a Work Group participant, where I experienced first hand the collaborative nature of professional development. Now in my role as Assistant Maths Hub Lead, I am dedicated to fostering these collaborative networks and supporting schools across our region to embed sustainable, impactful practice.
I am a firm believer that with the right tools and the right classroom culture, every child can succeed in mathematics, regardless of prior attainment, background, or starting point.
Karen Hill - Assistant Maths Hub Lead for Primary and Targeted Support
As Assistant Maths Hub Lead, I ensure the smooth running of the Hub’s primary programmes whilst supporting our team of primary and early years Local Leaders of Mathematics Education to lead professional development and change implementation in schools within their Local Authority regions.
I believe that a commitment to continually develop specialist knowledge and practice through collaboration is key to continuous progress. Therefore, sharing insights and best practice across the Hub and contributing to national discussions is a privilege to be a part of.
My Maths Hub leadership responsibilities also include contributing to the Hub’s overall strategy for raising attainment in schools identified as needing additional support which includes identifying priority schools.
