Angela, have you taken a look at the Getting Started page of this website? It is on the homepage left column. Also, the free book Education Is can be helpful and also Planning You CM Education (not free but affordable).
As for resources, have you done a search to see if any are printed online? Sometimes older books can be read on the internet (I’ve not looked at this particular module for this, though). Also, scouring through Amazon can yield inexpensive books. I’ve picked up books for not much more than the 3.99 shipping. Another idea is that as you look through your library, you likly will notice lots of books that have potential. I do not think that the SCM team would say that their list is the end-all in books; there are just too many. So, that may be worth a try. Booklists from other sources are an aid, as well. There was just a thread about this yesterday or so, and I think another one even earlier; I’ll look for it.
We have used both Analytical Grammar (are now, actually) and Easy Grammar. AG is more thorough in my opinion and therefore more difficult. The children like EG better, obviously 🙂 . Just getting started you will be fine to use EG.
Slow and steady! Easing into things will bless you and your children.
Blessings,
Cindy
