That said, you may not want to interrupt your curriculum.  I found what works best is a compromise.  Don’t think that your child won’t know that the public school kids are out for the day.  What I learned worked best was offering the student the morning off.  Sleep, play games, read, do whatever.  During that time I took 30 minutes to 1 hour to come up with a very interactive or ‘fun’ lesson that supplemented the curriculum that we were already working on.  I didn’t simply go into the existing curriculum, but did something more hands on and interactive.
