Question 401356: My 14 year old son has Asperger Syndrome and, up until this year, has always excelled in math, scoring very high in California Achievement Tests and working above grade level. I home school my children and have used various math programs, looking for the best fit (I have several on the autism spectrum and another with ADHD). My son is having a horrible time with Algebra 1 (which many children on the spectrum do) and I am hoping for any advice you can give. We have tried Kinetic textbooks, but it was not a good fit. We are now using Math U See, which seems to work, but he is still struggling...we are working on slope/standard formula and graphing at the moment. I would appreciate any advice you could give on teaching Algebra to someone who is a very concrete thinker so that I can get him through this. Thank you!
