When I first started teaching, I used to lesson plan with the thought of “I can’t wait until I’ve got plans for all my classes, so that I won’t have to spend so much time preparing for class!”. Now, after interacting with the #MTBoS (Math Twitter Blog-o-Sphere), I think to myself “I can’t wait until I’ve got plans for all my classes so that I’ll have more time to improve these lessons and find better ones!”
I only recently realized this change of mindset, but I attribute a large part of it to something I read on Fawn’s blog. Once again, I can’t find exactly which post it is , but it went something like “Each year I re-do fewer and fewer lessons. After about 10 (?) years, I’m now only re-doing about 70% of my lesson plans”. Wow.
 Looking for that quote did get me to go back and read ton’s of Fawn’s previous blog posts. It’s better than a gold mine over there!
