Mentally Adding and Subtracting with Regrouping: Developing Conceptual Understanding

Empower your students with the knowledge and understanding behind adding and subtracting with regrouping. Start with a context-based task using a setting such as base-ten dot materials or a 100-bead string. Leveraging a setting’s specific features will engender the mental strategies needed for adding and subtracting multi-digits. If you left Marria Carrington’s presentation Beyond Fluency to 20: The Power of Intentional Sequences to Build Fluency in Addition and Subtraction to 100 from the August 2021 Math Summit yearning for more, come back, and we will continue and add to the conversation. We will unpack what we mean when we say at Math Recovery® teaching is all about having the right task, for the right student, at the right time. This work is based on Dr. Robert Wright’s research and accompanying text, Developing Number Knowledge: Assessment, Teaching and Intervention with 7 – 11-Year-Olds.
