I home school in a state with very few requirements but I still feel the need to keep a detailed record of what we're doing in the event that, down the road, someone wants to see what we do each day. The laws may change or, at some point, some type of evidence may be required for college. Our state requires we do school 180 per calendar year, 5 hours each day. While we far exceed 5 hour days if we count everything we do I can easily keep track, kind of like a diary. With the subjects outlined it's easy for me to do back and see what we're not doing a lot or maybe spending too much time on a certain topic.
