### Ten Videos for Maths Lessons

I rarely show videos in maths lessons but every now and then I deviate from my usual lesson routine. Sometimes it's to help something stick in my students' memories, and sometimes it's part of the lesson's narrative. I thought it might be helpful to compile a 'top ten' short video clips for maths lessons. If you've been teaching for a while then you've probably seen them all before. But if you're new to teaching, you might find something you like here.

Clip 1

Finally, two of my favourite gifs:

I should also mention the best maths video website in the world, Numberphile, which is packed full of fascinating maths for both teachers and students.
