I purchased The Mystery of History, Volume II: The Early Church and the Middle Ages for my ten-year-old son this year. He LOVES it! He says of "The Early Church" section, "It's like reading about old friends," meaning early church leaders such as Peter and Paul. Now my son wants to learn to speak Greek, and visit Greece! (If only we could...!)
I am a huge history person, I love it, and I have been switching curriculum for years trying to find one I like. With a house full of kids, I need something that doesn't require a ton of teacher research and prep time, is chronological and thorough, yet makes history as exciting as it should be. We used MOH Vol. 1 last year and it was OK, but I wasn't hooked. We have used Story of the World (not detailed enough) and Veritas Press (way too detailed) and I was looking for something in the middle. Vol 1 covered most of the people and events I wanted, but the lessons were still too light on content and I had to do a lot more supplementing than I wanted to. I considered switching curriculum but thought I would at least look at Vol. 2 first. I was pleasantly surprised! The lessons are a bit longer and offer more background when necessary;there are fewer lessons, so if you choose to spend an extra day or two on a lesson you don't end up having to extend your school year; and, as an added bonus the black line maps were improved so areas of water are slightly shaded. That makes a huge difference with early elementary students. Now I am hooked. We will stay with MOH through all the books. Even with the faults of Vol. 1 my kids learned AND RETAINED a ton last year (The time line activity works wonderfully!). I highly recommend MOH 2.
