My daughter used We Hold These Truths as a source of documents, speeches and articles for American history and government. This collection has documents spanning the founding our our nation to the present and is a excellent source for deepening a student's study of history.
Every Notgrass study I have done, I have enjoyed. This series was very informative and one that I would highly recommend to other teachers and their students. I, myself, am a student and felt like the information presented was very clear, not only for those who knew little about government, but also for those who may know a little more about government already. The Biblical worldview is second to none that I have found. There are many good programs out there, but the Notgrass program is by far one of the best and most enjoyable that I have ever taken in my student years.
