These logic problems were designed to improve students’ deductive-reasoning and other critical-thinking skills. They also improve memory and reading-comprehension skills and encourage students to expand their vocabularies. Students read about situations, consider a list of clues, and use a matrix grid to eliminate possibilities and arrive at conclusions. In the complete Solving Logic Mysteries book, the logic mysteries are divided into three levels, with Level I containing the easiest problems and Level III containing the most difficult. Detailed solutions are provided. Children will love doing these puzzles!
