I made up a blank schedule for the kids and on each day, for each subject, I put either lesson or chapter and a ______. They write in the chapter, lesson or pg numbers each day as they work. This way if we miss a day we just continue where we left off.
I have a column on the side that tells them what I expect each day such as 1 lesson or read 2 pages or whatever works for that subject.
I am printing 40 of these week plans for each kid and having them bound into a pesonalized lesson plan book for each.
