Solving problems is part of life. Math is an extremely effective area in which to develop your students strategies for organizing thoughts to overcome problems. Each level of this book includes challenging exercises organized into four overlapping strategies: exploring patterns, organizing information, finding all answers, and using manipulatives. Each strategy is explained in detail and is followed by 12 related activities to develop and consolidate understanding. Some problems require a combination of strategies, and many of the activities are designed to encourage active participation.
