Hello, I’m Alison Kiddle. I’m a mathematician, educator and maths communicator based in the East of England.

I graduated with a degree in Mathematics from the University of Cambridge in 2002, then trained to teach maths in secondary schools. I left the classroom in 2009 to work for the University of Cambridge’s NRICH project, where I spent 11 years creating rich and innovative classroom resources for 11-18 year olds, and leading teacher professional development workshops.

These days I spend my time creating maths resources, running face to face and online maths workshops for students and teachers, writing about maths, and tutoring. I also tweet about maths and education.

If you’d like to get in touch about working with me on a project, Contact Me.
