I have all of those books. I used the first and second grade ones last year and just started the third. They are actually pretty easier to use, so don't worry too much. I usually do one lesson with the text book, then a lesson with the activity book, then a review lesson. The review lesson always consists of a game. I have 3 weeks per lesson though. I will start making some posts on here of lessons - although, I don't use the recommended layout for the lesson plans, but they are still not hard to follow. I will start some posts up here soon if I have extra materials, but, to be honest, the book if your best friend with these, there isn't too much reason to deviate. I go over section "A" then let them practice in pairs. Next I make them close their books and they are tested in front of the class by standing and speaking. Then I do the same things for "B" and "C." The activity book lesson takes a little preparation, but very little, and that is easy to follow. The game is Jeopardy. Every class is in competition with the other classes in their grade to win a prize at the end of the semester - they don't know what it is yet though. Anyway, I will appreciate it is anyone has suggestions, when I make some extra materials I will post them for all to use. Take care!
