For K-2, we have tried to just read lots of good books, and I did some phonics until dd couldn't stand it any more, and spelling. For third grade this fall, I think it might be time to add in some grammar study and some writing. And I'm wondering if there's any advantages to a formal literature program rather than just the "read lots of good books" plan that I've been following. What are your favorite resources for language arts? Are there good all-in-one programs, or do you use separate programs for grammar, writing, literature, etc.? I like the idea of progymnasmata-based programs -- have you had success with these?
