This is an article about a math educator and curriculum designer Maria Droujkova, who developed a different way to teach math. Instead of following the traditional sequence of arithmetic, algebra, trigonometry and Calculus, she suggests that many advanced concepts can be introduced through play stating that : " this progression actually has nothing to do with how people think, how children grow and learn, or how mathematics is built.”

The article is an interesting read, although I don’t necessarily agree that small children can’t do advanced arithmetic, as my LO and many other kids on the forum here have reached amazing results. Ironically, you can find the infamous article on the same page: “Study: Babies can’t learn to read”… duh!
Droujkova co-authored with Yelena McManaman, “Moebius Noodles: Adventurous math for the playground crowd". Pdf, Kindle and paperback versions are available here: http://www.moebiusnoodles.com/
I’ve just bought the book and I’ll try to share my thoughts about it here.
There is another book that has been on my wishlist for ages: “Calculus by and for Young People,” by Don Cohen. Has anyone tried it yet?
