The dilemma of where to place these books was a difficult question. The choices were where the math concepts were covered or when the story can first be grasped, in history or in math and as a read aloud or for the student to enjoy. Time will tell whether we chose the right place. Choosing the books was the simple part-they're fascinating. Children will learn of math concepts from the "puniest" characters imaginable. If you're an engineer your kids will relate well; if you're not your kids will benefit forever. Soft 32p
