I’m currently participating in the new teacher training for my new job. They call it the ‘Odyssey’. So far I haven’t met any cyclopses. However, I have finished this, my first ever math puzzle! I’ll explain more in the next post, but I just had to get it up because, despite it being a fairly simple problem, it is a huge milestone in my lesson planning. One of the projects I’d like the kids to do is to come up with their own geometry puzzle so we can create a book to self publish on Amazon.com. I was mildly freaking out that I was assigning them something far, far, beyond their capabilities, but I managed to do this one in about two hours. I’m going to give the kids six weeks plus two months of skill building so they have the appropriate tools to build their own puzzles. I think they may just be able to do it.

So without further ado, my first modern day Sangaku! If I haven’t made any gross errors (which is entirely likely) requiring me to take it down and fix it, I’ll post the answer to it in a week or so. Feel free to try it! (Unfortunately at this point it does require a calculator at the end unless you’re a wiz with non standard unit circle trig identities – over the next few weeks I’m going to try to alter it so no calculator is necessary.)
