If your learning disabled child will not put the effort in to accomplish work, and no reward or punishment could make them do it, how do you parent them to overcome their challenges?

I have a 15 year old mildly autistic and mildly dyslexic boy who has a difficulty with anything that has to do with computing or memorizing rules that have no deviation from the formula or methods. His largest struggles are algebra and anything that involves problem solving or decision-making.We've tried to motivate him through rewards but he is my creative child and has never needed actual products to entertain himself or make himself happy so there's no reward that would be great enough to push him through the struggles of learning. We've also tried punishment and discipline but he would rather be grounded to his room and creatively in his head then put the effort into his struggles. We've tried tutoring and helping him ourselves but he's unable to learn things through others he has to do it through personal experience. We try to put him in scenarios where these skills were necessary and he would Instead try to push the responsibility of these computations on us instead of trying to do it himself. I'm not really sure what to do at this point since having no expectations and high expectations do not seem to motivate him. I would even argue that you can't motivate him except through fear and abuse which we will not be doing. Does anybody have any experience with a difficult learner that refuses to do anything that takes effort?He's already received a total of 5 ease out of 12 classes his first year in high school. Even though next year will be his second year the school is going to be treating him like a freshman. At this rate if we don't have a solution for his learning difficulties she will not be graduating high school and he will be severely dampening his job opportunities as an adult. He also lacks in the social skills Department of life and has no friends that could help him or could be motivation to ground him away from. The only friendships that he has had this far are friendships that we created for him. All of in which our friendships we no longer have with their parents so the friendship with the children is gone as well. via /r/Parenting http://ift.tt/2uqTGJ6
