I started reading the new history of The Church of Jesus Christ of Latter-day Saints and couldn't help noting the first paragraph of the Preface:
"True stories well told can inspire, caution, entertain, and instruct. Brigham Young understood the power of a good story when he counseled Church historians to do more than simply record the dry facts of the past. 'Write in a narrative style,' he advised them, and 'write only about one tenth part as much.'"
It reminds me of Rudyard Kipling:
"If history were told in the form of stories, it would never be forgotten."
Stories are the most valuable tool in your teaching tool box! And notice the attention of these children in the painting. Nothing will hold their attention like a story told 'by heart.'
