What is a Number Talk?
An instructional routine where students mentally solve problems, share their thinking, and defend their strategies. Students reason about numbers while building connections to key conceptual ideas within mathematics. The goal is to develop fluency, or accurately, efficiently, and flexibly solve problems.
