Written by Rebecca Stark. The logic problems in Solving Logic Mysteries 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 vocabulary. The logic mysteries are divided into 3 levels, with Level I containing the easiest problems and Level III containing the most difficult. Youngsters may do the activities independently, in pairs, in small groups, or even as whole-class activities. Detailed explanations of solutions as well as a template for students to create their own logic mysteries are included. 96 pages. Grades 3 to 5.
