Math: Sandpaper Numerals, a 3-period lesson w/ Dominic

Okay, here is another impromptu demonstration with our little friend Dominic. It is Sandpaper Numerals - Math, part 1 with part 2 to follow. Remember, this was done "on the fly" and the first time Dominic had encountered a Montessori Math lesson. Notice how quickly he connects with the materials. He is clearly in the sensitive period for order!
