Methods used with my older son to teach following written directions:
1) Completion of preschool/kindergarten workbooks with a variety of clearly written directions.
2) Completion by me of a preschool math workbook with a very good variety of written directions. I wrote the answers in the book in marker and read/explained the answers to him while he played with Play Dough or ate.
3) Creation of flashcards demonstrating key concepts.
4) Write--numbered, very simple, with large text, and with pictures--directions that must be followed on a daily basis and post.
