"By failing to prepare, you are preparing to fail." This need not be the case if instructors use this handout of adages as they teach material about history, Rationalism, or America's Founding Fathers. The famous aphorism is just one of 20 of Ben Franklin's words of wisdom that can be found on this printable. But what does this expression really mean? As their assignment, students will use their critical-thinking skills to decipher various words of wisdom and then discuss their conclusions with classmates. They may also relate some of their findings to their study of the American Revolution as well as Ben Franklin's Autobiography.
