Oh yes good advise Nadia, I think I read about 6 weeks worth then printed 4 weeks worth and started. I had a very good idea of what to do by them. ALOT of it you learn by doing! Also be sure to keep your lesson plan in order, they probably don't have page numbers yet.
Oh and nothing you do is "wrong" provided you are having fun doing it remember to keep it light, pressure free and fun!
