I’ll add that I am not 100% sure if this is pure CM, but I did a combo of sight words and phonics. We went through the basic phonics teaching and threw in the sight word flash cards (the Dolch and Fry lists) with it. You can find the flash cards many places, but you can also google Dolch and Fry word lists and make your own. Since it was a big list of words, we only worked on the ones he needed at the time (the ones for the books he was reading) and once he had one down I didn’t keep drilling him on it. I am currently reading through CM’s first volume, Home Education, and from what I understand in her section on Reading, she did advocate teaching a combined approach. (and if anyone else has a better understanding of that writing, please correct me, as I am not completely confident I understood it correctly). All that to say, combining both phonics and sight words has worked well for us and my son has caught on to reading well, he can sound out words but also doesn’t seem bothered when a word doesn’t follow the rules and accepts it as a “sight word.”
