The math purists will probably bristle at me for this one but I loved this site that long time List member, Sharon Affeld sent along. It demonstrates 7 different ways to think about math concepts using fingers, lines and illustrations. I know — it doesn’t replace ‘real’ math skills but thinking about numbers in different ways may be fun for those who are strong at math and perhaps one or two tricks might help some struggling with a concept.
