• Resumen

  • 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 describes the thought processes of two third-grade students who were given a problem involving finding the number of dogs and chickens on a farm when they know only the total number of legs. Their solution strategies include standard mathematical operations as well as pictorial representations.
