I bought this method without much hope but I have to say that I have rarely been so glad for learning. My 9 year old daughter had great difficulty in retaining tables. She learned a table and forgotten the next day. We received the day after the order, she opened it and looked at all the pictures ... after 15 minutes it had withheld the results of some multiplication, looking as images. 3 days later she still remembers those images. She no longer drops the book and asks me to do exercises morning and evening. I am delighted. Bravo and thank you.
