If you're one of those lucky people who get an chance to do some globetrotting – perhaps for about a year – should you be worried about “losing” the academic time with your homeschooling high school student? And how will you continue in tricky subject matter like math and science?
I feel you won't be able to stop a child from learning. Traveling will teach them tremendous amounts that you simply can not learn from books! And you know, unschoolers do well on a regular basis. How much more could you have the capacity to do well if you're unschooling across the globe? Go for it! It will likely be a terrific educational fun, and also an experience not to be missed! Just expose your children to information all along the way. While you travel, have them read books on each location, plus learn some of the language. Learn naturally as you go along. The year is not going to be lost – it will enrich you and your children, and help to make them a more intriguing college applicant!
I can make a couple of recommendations. If you are planning to travel for an prolonged time, give some thought to taking a math book. If you can encourage your kids to be consistent with math, it will help YOU to feel like the year isn't lost. It is quite easy to accumulate 3 science credits for high school even though you take a year off. Math skills, on the other hand, are usually lost if they aren't used. If you have them do a little bit of math each day, it could help them to maintain that information. Even if they just accomplish a few problems, it can help keep those skills! If they are working at a high school level in math, consider getting an SAT work book, and just working on a couple of math problems each day.
