The SUM Centre

The SUM Centre at Haybridge

The SUM (Supporting Mathematics) Centre at Haybridge exists to provide support and training for mathematics teachers in Primary and Secondary schools.

We run numerous training courses throughout the year and can provide SLE support to your department. In recent years we have supported new Heads of Department to run their departments smoothly and effectively, we have trained experienced and new teachers, we have designed courses for non-specialists teaching mathematics, and we have visited numerous mathematics departments to offer whatever support they would like.
