When you are talking about slow travel, are you thinking a year, or a month? If you do a year, you can do the full school year with an online school. If you do a shorter time, then you can pull them out of school, but I think it depends where you live too. I pulled my son out of school for 3 weeks in Oregon, and they had to unregister him from the school, but in other places (I heard Britain?) you get fined if you pull your kid out of school for too long. I did have a friend that did a full year travel with her elementary aged girl, and she did the virtual school.
