This week's mission in the #MTBoS was focused on twitter. Sadly, I kept forgetting about it so now the next mission is up and I'm behind. Sigh.
So many of the folks participating in the various missions are middle school and high school teachers. Reading their tweets proves to me how much I have forgotten from those years. It's good for me to see this.
It is really fun to see the work samples and ideas from those levels of math content though.
