 And we want to thank Patricia Cunningham of Nazareth High School and Nazareth PA for sharing some of her teaching methods for free to choose. And if you go to the website, cspan.org slash books that shaped America, up there at the top, you're going to see teacher resources. There are lesson plans there. There are additional videos for each of the 10 books in this series. So I recommend getting on our website, especially if you are a teacher.
