      Is the Gathering going to happen this year? I enjoyed the last one immensely. I’d be very excited to attend again.

      Can't wait! I've never been so excited and enthusiastic about a mathematical gathering, can't wait to see my fellow nerds at this festival. I can't wait to show off my skills that I have gained from many years of math experience, I was once a mathlete ya know, I am the best of the best from my school, I have never gotten a math question wrong, because I will spend all night working on math. 3 All nighters was the longest I had spent on a math problem, some say I am crazy but I believe it's just my interest and enthusiasm in the thought process and understanding of math! I could go on and on and on and on and on and on and on and on and on and on and on about math!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I have never been to this gathering though, so I would definitely like some more information on the idea of this gathering. This also would be a great opportunity to meet people. I have never actual friendship before because I always isolate myself for days in a row... But it will be fine to find others like me!!!!!!

    Time for a little Puzzle: The two shapes shown in the applet have the same area. But where does the black square come from?

    Drag the points in the sketch below. What do you notice? What does this prove? How does this prove it? This is purposefully vague to let kids explore.
