The best thing about this was the group excitement the morning the boys discovered it in the classroom. After the two brother celebrated together Kal-El ran over to me, wrapped his arms around me in a big hug, and said, "Mom, you're AMAAAZING."
Now that Me Too is continuing his fraction work again, one clothespin on the Fraction Cabinet wasn't going to be enough. Putting up two blank clothespins and having the kids remember that Kal-El's is always ahead of Me Too assumes that Me Too will never surpass Kal-El...not very motivating! Nothing iPhoto and a little Gorilla Glue couldn't fix!
