I have to admit. I'm a spatial retard. Entirely stupid when it comes to objects in motion. Which makes it incredibly difficult for me to teach geometry. Proofs , theorems, and static shapes are no problem. It's when I need to move them that I encounter issues. Translations, reflections, rotations (aerate!!!!), and dilations, oh my! I'm a map turner. If it weren't for things moving, I would have finished my engineering degree.
So, now that I've admitted to myself and the world that this is my special spatial challenge, I've got to do something about it. I've always done their homework to look out for potential stumbles, but with the new Common Core standards, Geometry includes a lot of transformations. I'm struggling so much with them, that I'm wondering if either (a) I'm cut out for this particular assignment, or (b) this will make me a better educator. I'm leaning towards and hoping for (b). I will definitely confess my secret to my students. I believe that this will allow students to relate and feel hopeful toward their own challenges, and feel sympathetic toward me when I completely bungle something. Plus, they always get a decent giggle out of the similarity in the words spatial and special.
Stupid rotations. Stupid reflections.
