All Book Download,| Great Critical Thinking Puzzles | Critical thinking puzzles are not supposed to have any flaws. Some of these puzzles have multiple answers or are ambiguous. One example is early in the book. The puzzle 'Leftovers Again?' says that students are taught to turn a 1-ounce bag of clay into a statue. The quote in the book says, "For every five statues made, there is enough to make one more statue. Suppose a student is presented with 25 ounces of clay. What is the maximum number of statues he can sculpt?" According to the way it's written, most people, if not all, will answer 30. The book says 31. Incorrect! The puzzle says "for every five statues made, there is enough to make one more statue." It does NOT say for every five statues made, there is one ounce left over. If it were written this way, 31 would be the correct answer. That is just one example. Trust me on this. The book is full of them. Save your money and buy another book. There's a reason why it's selling used for $1.75.
