The growing emphasis on developing the mathematical reasoning and problem solving skills of young students makes this an ideal resource for elementary school teachers. It provides new and seasoned teachers with classroom-tested, hands-on materials, including over 200 reproducibles and black-line masters as well as practical suggestions for practice, evaluation and diagnostic assessment of reasoning and problem solving skills. The book is logically organized — first providing teachers with an overview of key concepts and basic suggestions for getting the most success out of what is offered. Following chapters unfold with classroom-ready activities organized according to the five stages of the heuristic process. Individual and group challenges encourage students to “Read and Think,” “Explore and Plan,” “Select a Strategy,” “Find an Answer,” and “Reflect and Extend.” In addition, there are collections of “Non-Routine Problems,” and of “Open Ended Problems Requiring an Extended Response.” Answers are provided to all problems, including effective strategies for accepting and evaluating answers to open ended problems.
