Mixed Concepts: Whole Numbers to Percents. Turns students into super math word problem-solvers! Math Word Problems helps students conquer the "dreaded" math word problem by teaching them when and how to apply the math operations they already know to real-life situations. Methods:The developmentally sequenced problems in each book are arranged so they cannot be solved by rote processes. Each problem requires its own thinking/problem-solving approach rather than applying the same solution process to entire groups of problems. Teaching Support: Includes answers, instructions at the beginning of each concept, and examples provided as models to reassure students about what is expected of them. 90 activities.
