My little boy is a 3rd grader. He's working from 9:00-2:30 with about a 30 minute lunch break. We're using Calvert so it seems to be a full day’s work. My husband has the same concern. We're doing a lot of extra stuff. He's in homeschool chess club, swimming, karate and co-op one day a week. I had to get that accounting mind of his to understand the fact that our son was doing all of this after school.
