### Math Links for Week Ending Sept. 22nd, 2017

Woo hoo, I saw a draft version of this at Twitter Math Camp this year and it seems that it is finally out. Transformation golf is a great way for kids to practice rotations, translations and reflections in a nice dynamic way. I've done a bit of work in this area here and here but the Desmos stuff is so slick your kids will love it.

In this latest episode of @MyFaveThm they ask @JSEllenberg what his favourite theorem is and it was a neat little ditty called Fermat's Little Theorem. Which basically goes like this. Take any prime number, say 7 and raise 2 to the power of that prime, 27. Then the answer when divided by the original prime 128/7 will always have a remainder of 2. This is easily used in any class where students have to work with expressions and primes. Listen here

I love it when teachers share their entire semester via daily posts. I think that besides this being a great exercise for teachers to self reflect, its great for other teachers to get ideas. In this case, @DaveLanovaz is giving us a day by day for his grade 9 academic math class. Check out the first post here and the rest that follow.
