Students say some amazing things. Back Talk highlights the learning of one or two students and their approach to solving a math problem. Each article includes the prompt used to initiate the discussion, a portion of dialogue, student work samples (when applicable), and teacher insights into the mathematical thinking of students. This article investigates a student’s understanding of the base-ten number system and how she uses her conceptions of place value to learn about the base-two number system.
