How can these activities help my child learn? They don't seem connected to any real academic skills?
These activities are all designed to help the brain work as a whole and will train the brain to use vision, hearing, or eye-hand coordination effectively so that the student is actually prepared to learn when presented with academics. Usually teachers, tutors, and learning centers just present more academics to the student. This will rarely help a student with learning disablilities. If he were able to learn by just being presented with information, then he would not be having trouble in school. The student needs to correct the problems that interfere with learning effectively in a classroom situation. That is what the activities do.
