Being a mathematics student is about critical thinking, justification and using tools of past experiences to solve new problems. Students who approach every topic as a series of steps to memorize are not learning math. They may learn Rules that Expire as they develop more sophisticated knowledge, such as Addition Make Bigger and Subtraction Makes Smaller. In this session we will explore how to replace some popular rules and tricks with teaching for understanding. Concepts explored will include number sense and place value, basic operations, order of operations, integers, fractions, and more. Math Makes Sense!
