Yes, it’s based on a 5 day week. As far as average time, that’s hard to say as there’s a lot of variables that would influence this. Some days have more work than others. Also, you as the parent know your child best and might choose to skip or lessen some parts. And each child is different in how long something takes. If I had to put a number to it, I’d say on average we spend about an hour and 15 minutes in total (which includes my daughter’s free reading time). I’d allow for an hour on your schedule…plus approx 30 minutes (or however much you decide) for free reading time.
