It always amazes me some of the things you can find on www.tes.co.uk and yesterday I found a real gem. For those of you that haven't read "17 Equations that Changed the World" by Ian Stewart, it is definitely one that you should read.
This wonderful resource sees the 17 equations turned into simple but effective posters. They are eye-catching, and bound to spark the interest of a few students in the corridor. The user who uploaded them suggests they are the perfect way to reply to the age-old question "Why do we need algebra?", but I think these posters have so much more to them. They are of varying levels, and so can interest any secondary age group, and they give students a nudge towards going to look something up themselves, as well as how far mathematics can really take you.
I'm going to be printing them off, laminating and putting them up next week, and I look forward to the responses from the kids.
I am a maths teacher looking to share good ideas for use in the classroom, with a current interest in integrating educational research into my practice.
