You should not use touch math because it has a lot of serious problems. It gives students the wrong information. If you tell a child to add a dot and a circle to get a total of three you are not teaching math because you can not add dots and circles because they are different units. The company claims the circle represents a dot. Most children can not understand substitution until grade four or five, so they add dots and circles. Many government curriculum do not allow substitution until higher grades so touch math would not be allowed. They destroy the number symbol by adding to it. You can not add to symbol without perverting the meaning. If you add a circle to a zero you change the meaning from "no units" to "eight units". These are only some of the problems with touch math. There just is not time or space for me to explain how bad touch math is for the teacher, student and the school system.
