I'm confused, isn't exploding dots just binary?

  I guess it's a way to teach children (or anyone) binary in a visual way, without talking about exponents.

  It's a visual representation of place value-- it doesn't have to just be binary; it can just as easily be base 10, or base 37, or base 1.5, or base x (polynomials). The full set of lessons is here: http://gdaymath.com/courses/exploding-dots/ http://gdaymath.com/courses/exploding-dots/

  Not just binary. It seems to be teaching the place value idea with a graphical representation. It would work for any base.

    In fact, it seems that the representation is also used to study polynomials and other objects.
