I just wanted to share this link:
Educational Software for Special Needs and UDL - CLICK!
This is a link our daughters OT shared with us while we were discussing typing programs for use in school. This gentleman has written this easy to use software without the bells and whistles of commercial software, for use with special needs and learning disabilities. The different programs address writing, keyboarding, math, scheduling and test taking - all are free to download. He actually suggests downloading to a flash drive so students can take them with them back and forth to school.
Hope they help someone else too!
