Logic for Kids [PDF ebook] 
All Aboard the Therefore Train!

Logic for Kids is intended to help parents take charge of the intellectual development of their children in a critical area: the acquisition of skills related to logical reasoning. Many other books, including math and science books, fail to treat logic as a subject in its own right, provide no special instruction, and expect students to figure out logic on their own. Without the corrective measures explained in this book, students will be ill-prepared to cope with increasing intellectual demands as they progress from grade to grade. These demands will become greater and more varied in college and once they embark on a professional career. Getting started in logic at the earliest opportunity is the answer.
