Easy to read math materials

During the past 6 years, my wife and I have owned a business which tutors a variety of students in remedial math ranging from primary to college to adult but mostly grades 7-12. During this time period, we have designed a number of workbooks and study guides for dyslexic and learning disabled students. These materials are used in tutoring sessions and the students also use them for private study. We have had an overwhelmingly positive response to these materials and students often ask whether we’ve made any more yet. They have commented that they are easy to understand unlike their textbooks or teachers’ notes on the blackboard. Our materials are step by step, large print, minimum text, minimum amount of information on a page so as to prevent cognitive loading, etc. Actually, most items are designed for a particular student. We also have guides to correct common misconceptions and errors I note in the students. We are blessed with instant feedback from our students so are able to revise accordingly.
I am looking for parents and teachers who would be willing to try some of my materials out on their children or students (no charge of course). In return you could let me know if you find errors or areas of confusion. Also, you could suggest in what ways these materials could be improved to be more effective. If you are interested, please send me your postal address and let me know what topics you are interested in. Most of this material is for junior high and senior high (grades 7 – 12). Not too much for younger kids yet.
