I purchased this book/cd set last year to use with my five and 10 year old sons. At first they balked when I popped it into the car's cd player, but I told them, "Let's listen to it every time we are in the car for just one week and then see how much we have learned." They were agreeable, so the experiment began! (I will note that we typically were in the car anywhere from 15 minutes to an hour a day, just running errands or going to and from school/sports.) Within a week, all three of us had learned all the presidents, their terms, facts... pretty much all of the songs! We would even sing them when we weren't in the car because they grew on us so much! I can't recall if we liked them immediately or not, but I can tell you that it was perfect for learning about the branches of government and Presidential history so they definitely were never annoying. I am actually purchasing a second cd because my original was damaged in my car and I want to have it to "refresh" our memories occasionally! I highly recommend this cd if you are looking for something catchy to teach these subjects.
