There are
lots of history texts out there. What's his reading level, what era of history were you hoping to cover, and does he like history?
I personally really like the ones by H.E. Marshall and other books listed at
mainlesson.com. They're interesting enough for
me as an adult to enjoy reading. I read An Island Story with my kids, and I was shocked at how little I knew about basic English history before I read that book. I've also liked books by Eva March Tappan, Alfred Church, and Mary MacGregor. You can search the History Books they have listed
here. The site is nce because you can read many of the books for free right from the website, or purchase paperback copies, or purchase them for Kindle.
For more modern history, I thought Susan Wise Bauer's Story of the World, volume 4, was okay. Some kids like it more than others. It bounces around quite a bit because she's trying to cover everything.
You might also look at the history books listed on Ambleside Online. And I hear Truthquest is very good. Really, there are so many good options, that I think history is the easiest part of planning a curriculum. The hard part is choosing just one or two from all the great books out there.
Answers in Genesis might be a great source for worldview -- discussion material that presents the different ways people think about evidence and events, and how a Christian can consider them without losing his faith.
