This engaging, colorful 152-page book teaches the most important critical thinking concepts every student should know. Many workbooks claim to teach or develop critical thinking skills, but most of these products never define critical thinking or try to teach the meaning to students. This book defines and teaches critical thinking in a way all students can understand through simple explanations, diagrams, and short, engaging activities. In addition to being a course in critical thinking, the activities in this book can be used to supplement lessons in all subjects.
