# Operations with whole numbers.

Shows that meaningful instruction in mathematics is dependent on multiple approaches, varied materials, diagnosis, and practice. Demonstrates procedures for interrelating addition and subtraction, improving multiplication instruction, and effective algorithms. Stress is placed on use of materials. Intended not as instructors' model, but to provoke discussion. From the Project on Interpreting Mathematics Education Research, Center for Cooperative Research with Schools, The Pennsylvania State University Summary Exp.ores procedures for interrelating addition and substraction. Shows materials, methods and strategies that are particularly effective. Focuses on the use of multiple techniques for misproving instruction in multiplic./ia metadataizes algorithms, which have been found to be particularly effective.
