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

Daily Lego Maths: Day 31

These three squares have the special property that the area of the two smaller squares together is equal to the area of the larger square. Can you find some more sets of three squares with this property?What happens if you arrange them in a triangle?

Daily Lego Maths: Day 30

Here is a rectangle made from squares.What do you notice? What do you wonder? What are the dimensions of each square?The shape was built outwards, starting with the smallest squares. What dimensions of square would we need to add next? Where would we add it?


I create maths resources and ideas for use in classrooms and workshops.
If you find any of my resources useful and you want to support me as a creator, you can support me on Ko-fi

Paper Plate Circle Theorems – a demonstration or lesson activity using paper plates to show some circle geometry.

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.

Probability Horse Race Simulator – A GeoGebra version of the classic horse race maths activity
