I just wanted to say that TOG gets what I consider a "bad rap" sometimes b/c some people find it's a giant planning monster. I wanted to offer some encouragement and simplify that process a bit. I'll make this sound easy, b/c I honestly think it is.
1. Choose books from list. Since there are so many subject areas in TOG, go to that area and choose the book. I spent about 1 hour choosing books in 4-levels for 2 Units. I follow the SL "book basket" by often getting the other books (I didn't choose as spines) and having them lying around for personal enrichment.
2. Decide your daily schedule. I.e. Monday - vocab, reading; Tuesday - mapwork, reading; Wednesday questions, start project....you get the point. You have to design what days to do what, and you may try a few things before you find your comfy groove, but since we all handle when we teach a variety of subjects M-F, we are totally capable of this step too.
3. Plug in materials, all provided by TOG, into your daily schedule (#2) This takes as much time as counting book pages and dividing them up, printing your copies, and having them ready for your dc in whatever way ya'll school. The beauty...it's all there for you.
The most time consuming, extensive portion of the program is Teacher's Notes, which does take time to read. Whether or not you study them, take notes, etc. is up to you, but if you have dc in Grammar Stage, this will just be for your own education. If you have older dc, then you'll need to do this for teaching. It takes less time than reading all of their materials, though, and the benefit is growth as a person and as an instructor. The thing here is that you're not planning anything b/c everything is laid out for you. You're preparing by reading.
Many people don't realize that TOG promotes self-planning for D and R students...so you're kinda skipping step 3 before you know it b/c the dc are doing that part!
All that to say, when you first look at the girth of TOG...it's intimidating...but once you pass the TOG Fog, it's a breeze, and I've never felt saddled down by daily plans that don't match my family, nor crazy b/c I have to figure out every little details. The little details are provided, I just decide how I want to use them, or not
I hope this helps or encourages someone who might have been intimidated to give it a try. It is a fabulous program and has brought the joys of history to my family in ways I didn't even find possible.
