I'm trying to plan the year for our homeschool. We school pretty much year round, which lends us great flexibility. Legally I am required to have 180 days of attendance for all of my children between the ages of five and 18 years, equivalent to about 1000 attended hours in a year. Going all year means we do four hours a day, five days a week. These are not like hour-hours, but are attendance hours, and are better thought of as "lessons." (In other words, I don't teach them all for four hours every day. That counts the time they read to themselves or work alone and the time they discuss what they have read or worked on with me.)
It is MUCH easier for me to take attendance with Charlotte Mason than it was when we were unschooling. It always felt like unschooling took so much explaining, especially to the governmental types. For such a simple concept it can be remarkably difficult to understand, if you think children only learn when they are taught.. When we were investigated by DHS, Faith was the only child of school age, and she was five - it's not difficult to demonstrate unschooled learning in a five-year old. But with older kids, it's trickier, or it can be.
Since we're studying the Middle Ages, we'll be covering about a thousand years, approximately 500 to 1500 AD. Conveniently, Our Island Story and A Child's History of the World both finish up the Middle Ages at chapter 61! This would be even more convenient if they both started at the same chapter. But... no. A Child's History of the World starts the Dark Ages at chapter 40, and Our Island Story starts them around chapter 8.
(That's if you consider the Dark Ages to have started at a different time on the continent than in Britain, which I do. If you don't think that, then OIS starts it at chapter 12. But I digress.)
259 pages for OIS, 93 for CHOW. So what we'll do is read two or three chapters of OIS for every one of CHOW. There's several read-alouds in there too. I think they'll be for another post, as will our math plan...
