Our past includes using BF Early American 2 years ago, and then moving to VP and some Ambleside Online. We really love Ambleside Online. My problem lies in trying to pull it all together with copywork, narration, etc.
Here is some info about my children and my thoughts about placement:
We will all continue to use Phonics Road and Singapore Standards.
9 yo son/3rd grade: Phonics Road 2, Singapore Stds 2B, currently reading lots of picture books, finishing Adventures of the Northwoods bk 5, Bears on Hemlock Mountain (one night), he has been reading Little Pilgrims Progress and drawing out and labeling a map to go along with it for AO. He's doing dictation of 2-3 sentences with PR once a week. I have not required any written narrations from him and I'm very happy with his comprehension. I'm ready to see him writing his own narration. I'm not sure which guide this would be, he placed solidly in Bigger and Preparing. I think he would be overwhelmed to write 4 sentences right now, but I do think he could build up to that soon.
8 yo son/2nd grade: Phonics Road 1 accelerating, Singapore Standards 2A, just starting to read early readers with some speed and fluency, but still needs work. Good with narrations (all my kids so these CM style, no summary style yet) and copywork of 1-2 sentences. I don't think he is ready NOW for narrating and writing them, I think he is going to need a step in between. He placed in Beyond and Bigger with the placement chart.
7 yo daughter/1st grade: Phonics Road 1 normal speed, Singapore Standards 1A, knows sounds and can form letters. She is my slow going one and very much a day dreamer.

5 yo daughter/pre-k: Just finished R&S ABCDEF Books. Just shelved Phonics Pathways, she needs a little more time. I'm contemplating where to take her right now. I have a Super Kindergarten workbook, but we did a lot of that in the ABC books. I'm going to bring her through the alphabets (maybe with Super K book or Getty-Dubay A, or maybe both?) and try again with PP in a few weeks. She is definitely one that wants to do school. She throws her workbooks on the table every. single. day. ready to do school! I feel like she is ready for more simple math too. She is very busy and needs to work on sitting and listening. I haven't really tried to place here in the chart.
2.5 yo daughter
son due in the summer!
I'm sorry that is long, I'm trying to be thorough to get good placement for my children, I think that will be extremely important to using HOD.
Some guiding thoughts for me as I try to think through this:
1) I'd like to only use two guides for right now
2) It would be nice to schedule it so my children can make it all the way through hs with HOD without missing a full year
3) I've read some threads where the suggestion is to not be working through consecutive guides
4) I think we should start at 1/2 speed and pick it up as we can.
5) And of course, the most important goal is to place them in the guide for their skill levels, but I don't want to start them off in something that would be behind. I would like to see stretching.

I've bought LHFHG and Bigger and have been looking through them. My first thoughts were to put my 8 & 9 year old sons together and my 7 and 5 yo daughter together, but I think my boys need to be separated. My oldest is a alpha, a sweet one, but can be dominant. Their skills are different too, my 9y can easily write from dictation and 8yo is just doing copywork. The girls are pretty far apart too in skill, etc. I do want my 7yo to be challenged also.
I was actually thinking of using Preparing for my 9yo and putting the next two 8yo and 7yo in Bigger maybe Beyond? I could possibly work with my youngest daughter and add her in after I got the hang of things. I would have to figure out storytime, if I would use DITHOR or just let them read them, and if I wanted to read aloud some of the extensions (not all, maybe just some).
Thanks for listening as I've tried to be throughout, but it has turned out being long-winded too. I'm all ears for comments and advice. Thanks so much.
