The Thinking Toolbox: Thirty-Five Lessons That Will Build Your Reasoning Skills

The Thinking Toolbox is the practical, hands-on companion to the Bluedorn brothers' bestselling The Fallacy Detective, and it is one of the most approachable logic resources a homeschooling family can own. Where The Fallacy Detective teaches students to spot bad reasoning, The Thinking Toolbox focuses on building good reasoning — giving learners a set of practical "tools" they can pull out whenever they need to think a problem through.

Across 35 short, illustrated lessons, the book covers when it is wise to argue and when it is not, how to support an opinion with evidence, how to tell the difference between fact and opinion, how to read and evaluate sources, and how to approach a problem like a detective gathering clues. Each lesson is written in the same warm, funny, comic-book style that makes the authors' work so popular with reluctant readers, and every concept is reinforced with engaging exercises and real-world projects — including hands-on activities like analyzing a "crime scene" or building an argument from scattered evidence.

Designed for ages 13 and up but accessible to motivated younger students, it works beautifully as a once-a-week logic course over a semester and needs almost no teacher preparation, making it ideal for independent work. Families often use it right after The Fallacy Detective to round out a full year of informal logic before moving on to more formal study in high school. Clear, secular in its reasoning content, and genuinely fun, The Thinking Toolbox earns its place as a homeschool staple for grades 7 through 12.
