I have 5 children and have used AO for 3 years now. My oldest is 9 and doing year 3. My 3 younger ones are 6, 7, and 8 (also a 1.5 year old) and although most people over at AO would advise against it, I combine them. From the beginning I have taken those weeks that are laid out and turned them into more like modules. We do module 1 before we move on to module 2, etc. My oldest does much of his reading on his own. We have a set time that we do school activities, usually about 3-4 hours a day, with less for the younger ones, and we work with a loop schedule. Our day looks like this:
8 AM
Breakfast/Morning time: 1hr (everyone together)
Proverb (5min), Bible Reading (10min), Hymn (5min), Fun Read Aloud (15min), Folk Song (5min), *either* Tales from Shakespeare, Parables from Nature, Pilgrim’s Progress, Composer or Artist Biography, Picture Study (10min)
9 AM
Next, oldest goes off to begin his work on his own. This includes scheduled readings, math, copywork, dictation study, memory work, French on CD-ROM.
Younger ones take a break for 30 min to an hour (outside, weather permitting) and I join them with the baby.
10 AM
After break, the younger ones come back together for about an hour session and we work completely from a loop schedule. I have taken all the AO readings for years 1-3 and placed them in a list by subjects – History, Biographies, Natural History/Geography, Literature. Our Loop Schedule looks like this: Copywork, History, Memory Work, Math, Biographies, Phonics, French, Natural History/Geography, Poetry, Math Drill, Literature.
We just work through the list, doing whatever comes next. If it is something like Math or Phonics then I get the older one started first and then move around to the younger ones, offering help as needed. For the readings, I just do whatever is the next assigned reading in that subject and read for 10-15 min. including taking turns narrating.
11 AM
After this session we have lunch (listen to composer now) and immediately following lunch the baby goes down for nap I work with my oldest for an hour on Latin, Plutarch, Shakespeare, Poetry, and if he has questions about math while the younger ones go back to playing.
12:30 PM
Oldest will finish up some work if needed and younger ones come back for a shorter session, about 30 minutes before we end our school day at 1pm. Everyone is done at 1 pm and we stop wherever we are and pick up with the next thing tomorrow.
Later in the evening we have a Free reading time. This is 20 min where everyone must have a book to read quietly to themselves, or a picture book to look at for the non readers. And we also do a free read aloud to everyone before bed.
I hope that was not way more info than you were even looking for but I just wanted to give my example of how I make it work with multiples and some combining. I will move each of my children out of the younger combination “class” as they reach the ability to read most of their school books for themselves and then will put them in the year most appropriate for their level. The littles have approx. 2.5 hrs of school time / day plus some reading practice in the evening with me or dad and 5+ hours of free time. The oldest does about 3-4hrs on an average day with 4-5 hours of free time. The baby just sort of hangs out close by while we are doing work, playing with toys or drawing on chalkboard, or sitting in a lap or someone holding him or……
