Photo of AlisonHello, 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 and videos, running face to face and online maths workshops for students and teachers, writing about maths, and tutoring. I also tweet about maths and education.

Using GeoGebra to explore linear and quadratic graphs – four GeoGebra applets and some notes with suggestions of how they can be used in the classroom.

Noticing and Wondering – a gallery of photos which can be used in the classroom to provoke mathematical thought and discussion.
