What is the I-Math Program? The I-Math Program is a collection of nineteen different mathematical problem-solving activities. Each title, which contains from one to eight pages, starts with simple questions that serve to establish your basic level of understanding of a concept that will be covered in that particular series. The questions then slowly become more complex as variations to the problem are introduced.
