So I am really excited, the first (and only in this area) math meet is happening at UW-Platteville in a couple of weeks. I am big believer that everyone can be part and this year over 1/2 of the High School has signed up. Right now it is 52 out of 92 about 56%.
We practice during lunch as a group and support each other on the team; all the while setting individual expectations and experiencing a great, fun, off-site math day. Some students are there to do their best and hope to get 1 out of 10, while others are going for a perfect score. We all go -- I have a "lead" team but everyone works and plays together and we celebrate the day together.
And this works, I am actually able to use the math meet as a carrot for students not completing work or struggling. (Can't take a student on math team that cannot finish homework, etc.)
Students will follow their leaders, so I get the student leaders on my side. It is slow process that has taken years... But I really feel we are reaping the rewards now.
