This is a great tool for either introducing a new topic of US history or reviewing after the topic has already been taught. I've used it both ways and it's worked well either way. I think it would work best for ages 7+ but my son who is almost 4 will from time to time actually sit through an entire episode(although probably isn't retaining much information haha). That being said my DD who is 8 LOVES it and has asked on more than one occasion this summer to watch it, just because she enjoys the series! In my book that is a win!
My daughter & I used to watch this show years ago when it was on tv. She was about 10 years old then and loved it. I thought it was very well scripted and historically accurate (I am a teacher). When I saw the dvd recently I had to buy it for "old times sake." We recently watched a few episodes and still enjoyed it.
Kids are enjoying this immensely. They are learning about History while at the same time having fun. There is some references to God. I would like it if it was more Christ focused but it did not claim to be, just would be my preference. Does teach good morals. Will purchase more of these for the kids.
