This book offers a collection of fun, easy-to-use detective cases for grades 4 - 12+. That is a wide grade range, but anyone who can carefully read these cases and is willing to study the evidence can solve them. They are not solved through tricky logic or advanced math concepts.
Some cases may be more challenging for younger students, but teachers and parents can always provide hints if absolutely needed. The cases develop critical thinking skills by requiring students to ready carefully and analyze and synthesize information to guide their decision-making. The cases also develop observation skills, reading comprehension, deductive and inductive thinking skills. The ability to identify and evaluate evidence is the very heart of critical thinking.
