Recommendation for Reading help with Dyslexia

[RealLifeMama]

My almost 12 year old is pretty severely dyslexic. Two of my other kids have mild dyslexia, but his is severe. He was getting private tutoring/therapy up until two years ago. That is not an option right now. It is mainly his fluency and how it takes him so long to sound out a word. I gave him an AAR level three reader to read today and in 10 minutes, I think he had maybe read four pages.

I am really stuck as to what to do with him. We used to have some computer based programs that helped, but we can't really use them right now. I am looking for some paper/hard copy stuff to do with him that will not take more than 20 minutes a day and that is super low prep. I wish I had more time to devote to it, but I have six kids schooling, and they are all at different levels and stages. I really only have about 20-30 minutes per kid one on one per day for school.
I looked at AAR, as that is really working well for my nearly 8 year old, but he would probably hate all those little activities in the student activity book. I saw something on Schoolhouse teachers, but I was just confused.
Any suggestions?
