Kate Mom of 1 – As far as how “necessary” these are, I think that’s up to you. I know lots of people here love using these books, but after looking at them, I felt like they were redundant for us. We already read and occasionally memorize poems, do nature study and picture study, narrate what we’re reading, and occasionally talk about grammar/punctuation issues as they come up in her copywork or things she writes on her own. Personally, I prefer this as it is all integrated into our other subjects so it’s one less thing I have to add into our schedule, but she is still get exposure and practice to all the skills in these books. I feel comfortable continuing with what we are doing now, and we’ll do a more formal grammar curriculum once she hits around 5th grade or so, as per CM recommendations. On the other hand, if you like having these things laid out for you, or if you are new to CM methods and trying to figure out how to make it all work, I can see how these books would be really helpful. So I’d say take a look and see what you think, and go with your own intuition if you think it will help your dd with the skillls she is weak in or not.
