This book provides puzzles, games, and mathematical activities for students in elementary grades. Number concepts and arithmetic are common topics. These classic math, logic, and word-problem activities encourage students to become flexible, creative thinkers while teaching them to draw valid conclusions based on logic and evidence. Each activity works on specific reasoning skills such as visual discrimination, mental and written computation, sequencing, logic, and deduction. Practicing these skills gives students the ability to solve more difficult math, science, and work-related problems in the future. (Includes answers to questions and puzzles; reproducible for single-classroom use.) (ASK)
