I cant lie this is overwhelming having to find and buy so many books for each subject. Im transitiing from public school and have alot of adjusting . lol
You can see samples of the commentaries online at Amazon or CBD and decide for yourself. My youngest is going to be a second grader and we just wrapped up Module 1. I thought the commentaries got a bit long and wordy. As far as the other books are concerned, with the exception of the two newest SCM titles, we used them all. The grade 1-3 specific books were huge hits 🙂
Also, take a deep breath and relax. If you skip a few books, no big deal. If you sub-in books that your library has, no big deal. Your student is young and you will hit this time period again 🙂
