Navigating through Problem Solving and Reasoning in Grade 3

Problem solving and reasoning are students' processes of actively applying what they know to new problems from diverse areas of mathematics. Knowing a variety of mathematical ideas is insufficient unless students can draw on, integrate, and use them to solve challenging, complex problems. The Navigating through Problem Solving and Reasoning books for grades 3-6 present hands-on investigations that nurture reasoning and problem-solving strategies in each of the upper elementary grades. In investigations for grade 3, children reason about place value by making and using pedometers, understand related changes in two quntities by exploring parade formations for thirty-six marchers, and analyze data by devising rules for earning reading certificates. Students apply mathematical ideas from the five main content areas-number, algebra, geometry, measurement, and data analysis. As they work, they infer, generalize, reason by analogy, recognize relationships, and make representations, and they also guess, check, and revise and verify their results.House, Peggy A. is the author of 'Navigating through Problem Solving and Reasoning in Grade 3' with ISBN 9780873535571 and ISBN 087353557X.
