Trading "Greens"

Your child is welcome to save up any green color squares they earn for behavior here at school (I know many already do save these slips of paper at home). When students save 15 green squares—whether that takes just 15 school days or longer than that—they can bring their green squares back to me (as long as they aren’t wrinkled or written on) and trade them in for something special. They might earn a little prize, and I will be able to reuse the color squares. Thanks!
