On the first lesson for the quarter note you show a book are we supposed to buy the book? Where can we buy the book? Also, are you going to have an intro video concerning needing to buy the books? I have one other question it might be my phone, but I cannot turn it sideways to enlarge the video to be able to read the book that you have on the keyboard.
Yes, there is a book. The “About” page should describe it, and the welcome page for each curriculum has the scope and sequence as well as direct links to amazon to buy the books you need.
