I had a large set of them, they're great! They feature an historical figure and some sort of value and tell a story of how that character learned the meaning & importance of that value, set in a short story of something real they did.
For example in the Value of Believing in Yourself, you learn about how Louis Pasteur (best know for his milk-pasteurization process) developed the Rabies vaccine even though people said it couldn't be done.
In the Value of Helping, we learn about Harriet Tubman and the way she helped slaves find their way to freedom via the Underground Railroad.
There are 24 books in the set, I believe, and you can order them individually or as a set. Great character lessons for kids as well as history lessons.
Kindness, Respect, Creativity, Fairness, Honesty, Humor, Imagination -- just a handful of the topics covered in this series. Historical figures like Madame Curie, Helen Keller, Confucious, Jackie Robinson, The Wright Brothers, Sacajewa, Abraham Lincoln, Beethoven . . .
