It’s MUCH easier the second time around. I’m trying to get it done more though, it is a good book. Anyway, the keys for me are first, at some point (a week before or 10 min before), to read the lesson. Especially any parts I’m not sure on. If I can’t do the whole lesson I’ll read the objectives and then whichever part we are doing that day. Second, send the kid(s) on a scavenger hunt to find supplies (helping as needed).
Then start the lesson, skimming along as needed. It helps that my guinea pig, wait I mean my eldest :D, is an easy-going child. Very forgiving of back-tracks or mistakes on my part. For the younger kids, including the black & white perfectionist middle son, it is much easier, because I am familiar with the lesson and I’ve done the more advanced lessons.
I also delayed the book. My goal is book 1 in 3rd & 4th; book 2 in 5th & 6th; book 3 in 7th & 8th.
