Don Cohen is a math magician who is teaching calculus to young children. Pretty phenomenal! I love the map that is shown above that he built using examples of how these young children are figuring out complex calculus problems. I like that Don uses ordinary language with these kids–for example, instead of one-half, he calls it one-twoth. An inspiration to us all. The way I see it, if 7 year olds can figure out calculus, all children are capable of learning. Thanks Don!
