We send papers home every Thursday and one of my students brought his back with a note form his mom. I marked an answer wrong on two different papers.:unsure: She was not rude or anything in the note. I just feel like a dummy! It was just my oversight...I sent her quick note saying I apologize and let her know I corrected the papers and thanked her for catching my mistake. Being a first year teacher I feel like I keep making so many mistakes! anyone else mark something wrong by mistake and the parent caught it?
