Subtraction, Mini-lessons and Representation

By Cathy Fosnot

It's time for another season of The Math Pod with Cathy Fosnot. In this series, Cathy and her team explore "Developing Automaticity of the Basic Facts and Computational Fluency using Strings of Related Problems". Join us for a six-week journey through the exploration of Mini-lessons, intentionally-crafted strings, and the fascinating world of Cathy's mathematics landscapes for elementary and middle school students.

Subtraction is an operation that is complex and can have different meanings in different contexts. Often students (and adults) think of it in a limited way as the action of “take away”. In this episode, Laurie Clayton, Chrissy Chabot and Melissa Peddie team up to explore and further develop our understanding of the richness of subtraction.
