Oh my!!

Soooo, my kiddos just bombed their quiz...well, most of them.  I have been so excited, because they have been doing so well...Then, this happened.  So, I guess this is where I learn to go back, review, find out the problems and still keep up with my lesson plans as scheduled! While I was grading the quizzes, I wanted to scream, "WWWHHHHHHYYYYYYY????" It feels like I went over this stuff over and over, but I guess a different approach is needed...I know it is partly their fault for not doing well on the OPEN NOTE quiz, especially when I see some not taking notes! (Grr....) But, I can't help but keep thinking, what did I do wrong?
