OK I saved the best for last. Here is my back wall. The math sign was inspired by Julie Reulbach though honestly I don't remember what, if it was a picture on her blog? I went to check her archives back to when I saw it but its not there but I do know the idea came from her so I wanted to give credit where credit is due.
I am so looking forward to school starting tomorrow and sharing my classroom with a whole new group of students. I hope that Mrs. Olsen's World will bring them a greater love of math and a desire to keep learning!!
