I've heard that many here have used these and we just got the first one in the mail from the author. $19 for an autographed book is too cool. Could you tell me more about them in the sense of how you have integrated them and where they fit into a curriculum? (I already like that things are explained, not just shown.) My DD9 is currently using ALEKS and I'm not sure where to go as we look at finishing up LV 5&6. She doesn't love math but sees it as a means to an end with her true love being science. I think she would do better if it was more...well, fun.
