Thanks to everyone who entered the "Do you have a great maths teacher?" competition. We received lots of deserving nominations - clearly lots of great teachers - but here are the three entries that impressed us most of all. Copies of "The Simpsons and Their Mathematical Secrets" by Simon Singh on their way to the winners.

Luca at Franklin College nominated Mrs Emma Bell, telling us: "When I first started secondary school, I wasn't interested. I couldn't see the point in anything and didn't make any effort. All but one teacher saw the potential in me, and encouraged, inspired and enlightened me to see the point in things (decimal or otherwise). That teacher was Mrs Emma Bell. After 5 years of having her as a teacher at school, I am now  well on my way to becoming a teacher myself. If I'm half as good as Mrs Bell, I'll be great. "

Georgina at Mount Grace Secondary School nominated Miss Boachie-Donkor: "My maths teacher is an incredible lady. She is a lady of manners, profession and dignity. She's not just my Hero Maths Teacher, she's also the lady that promises me a 'C grade' at GCSE, and that to me means the world - no pressure, Miss. Her personality has changed the school for the better. She is my key to success. Now is that enough to be my maths hero? I think so."

Finally, Pierre at Narrabundah College in Austalia, among other things, explained that his maths teacher Ellie Filler "… taught us dividing by zero makes calculators cry."
