Just two bits of information that people might be interested in.
The first is that the current issue of Heart of the Matter magazine is out. This magazine usually has some good articles.
The second is that I've found yet another really neat curriculum (There are so many great ideas out there - I could spend a fortune!) This one is called Five in a Row, and it's a unit study program for younger children based on classic children's books. It looks really interesting, and it's pretty cheap to buy the teacher's manuals ($25-$35 a year). I'm guessing you could find most of the actual books at the library. They do programs for preschoolers and older kids, but I'd be considering it for the first few years of elementary school.
Anyway, have a look!
