Now I need some thoughts on Math and Language Arts for struggling high schooler

I had mentioned in another thread that I am going to be meeting with my evaluator to come up with an ‘IEP’ for high school for my DD who will be in 9th grade in the fall. I am confident about science and history ideas, but Math and Language Arts are my biggest concerns. I want to have some ideas to present to my evaluator, to give her a springboard.

My DD has language based disabilities, including dyslexia, receptive and expressive language difficulties, very poor spelling, etc. But, she loves to write. Putting a lot of focus on grammar and spelling rules is futile. I was thinking that I need to focus on her writing, vocabulary, and spelling the most. She loves journals and is always writing in them and even tries to take notes during the preaching at church. I think she just needs to be doing something with her hands to concentrate. But, it is probably not helping her spelling, because outside of school, she is continually writing and spelling words wrong, and I have no way of keeping up with it and it is her personal journal. I was looking at IEW. I like their method. I have also been using Spelling Workout with her, just for some spelling practice. I include a little grammar here and there. After reading all this, would anyone have any suggestion, like additions or changes to what I am thinking. I am just brainstorming right now, but any suggestions would be helpful.

Also, she has a more than moderate disability in math. She has not memorized her multiplication facts, but I believe she is understanding the concept. The neuropsychologist said not to focus on facts and let her use the calculator, but I like for her to be doing some thinking. Using a standard math program does not work because there are concepts we have to skip because we need to focus on life skills areas. The psychologist said to focus on time management, money, and the evaluator added measuring to the list. This year we used some workbooks that focused on one concept, like clocks, calendars, and money. Working on one thing for weeks really helped her in those areas. I used to have Math on the Level, but I sold it after I got results from the psychologist. Maybe I should have kept it, but it is costly to buy and I didn’t feel we were getting much use out of it. But, being able to choose the concepts to work on was helpful. I do have SCM’s Pet Store Business Math, but I have not started that yet, because I feel DD needs better money skills and multiplication knowledge before we use it. I have a Grocery Cart workbook, which would help her in measurements and money. I just don’t know how to go about planning for high school credits. I want her to earn some kind of diploma, even at a remedial level. I’m just not sure what would be appropriate materials to use, given her special needs. Any suggestions or recommendations? Thank you.
