My son just finished IM last week. The biggest gains I have seen have been in sequencing. What month comes before Nov? What number comes after 10,000? etc
I did not see a jump in reading and the jury is still out on the writing. He already reads at grade level. He may be writing a little faster but the spelling and sentence structure are still a problem.
I have seen a jump in independance. When I say it is time to do your homework he sits down and just does it with minimal help. His math abilities have really jumped. He also does better at visual things like reading a clock or analyzing graphs. He will now sit down and draw pictures which is something he never wanted to do before. (I also have done some visual perception exercises that may have contributed.)
I am taking him out of the in class support classroom at his request. He just doesn't want all of the extra help. I don't think he would be able to handle the reg ed class if not for IM. (Fingers double crossed that this will work)
I have also seen improvements in motor abilities.
Overall I think it is an amazing program. My son's timing in the end after 24 sessions was overall 42ms. His original score was 250ms. I will do this again with him to get his score even lower. We are on a break for now.
