We give them sails when we teach them to read. I have been selling this course across the country and have had orders from abroad. I have managed to keep the price very low and am shocked at courses that charge a lot for what is actually quite a simple thing. It is a write-in workbook with all the instructions and exercises right there. Videos available for the first two books can be used alone or with the book.
Some parents buy the book only, some the video only, some both.
Any of these systems works. I have had very enthusiastic results from parents who are thrilled to hear their toddlers going around the house identifying toys by sound of the first letter and trying to sound out words. I am not pretending my method is the only one that works. Many methods work. But this one does, and very logically.
