I've always been using this method! I also try to build a small list of key points too. it's a really good brain exercise. I sometimes use Coloring pages like Wild Kratts Coloring Pages in the process. It helps me to focus.
Thank you for sharing these free coloring pages. I'll print out some of these for kids at our school. I have also found more free coloring pages here http://www.coloringpages4kidz.com/home/
