MathJam @ NWMI
MathsJam is a monthly opportunity for like-minded self-confessed maths enthusiasts to get together in a pub and share stuff they like. Puzzles, games, problems, or just anything they think is cool or interesting. We'll be putting on a special session at NWMI to give you a taste of what goes on (minus the pub). This is an opportunity to do some hands-on math, focus on the joy within mathematics, socialize and to hopefully bring some ideas back to your classes. (Benjamin Leis is a system programmer and math enthusiast. He has been leading math circles at the elementary and middle school level for the last 5 years and is a recent NWMC presenter).

Randall Creek (45 min)
The Three Square Problem (No, it's not nine!)

Have you ever worked on a really challenging math problem, and then had the answer elegantly present itself and/or connect unexpectedly to some other cool branch of math (like the Fibonacci numbers)? Well this is not one of those problems, ha ha j/k. I am still blown away by the solution! And the best part is that there are multiple points of entry, so it is developmentally appropriate for all students and teachers :)
