I can tell you how it looks in our house. The children I do family subjects with are 6th grade and 9th grade so they can sometimes handle a back-to-back reading, though I try to avoid it. Typically it looks something like this:
Mon:
Bible
Picture Study
Latin
History
Music
Tues: Co op
Wed:
Bible
Poetry (a bit more lively than just a reading)
Latin
Geography
History
Thurs:
Hymn
Bible
Timeline
History
Fri:
Bible
Geography
History
Logic
Art lesson
Nature Walk
Of course we mix it up also, depending on our mood, something might even get skipped altogether (and I don’t stress on it). Family literature includes my 11th grader and is during lunch. I always eat first and then read while they eat.
