back talk: Abby and the number line

Kurt J. Rosenkrantz 

March 2013, Volume 19, Issue 7, Page 464

Abstract:
Students say some amazing things. Back Talk highlights the learning of one or two students and their approach to solving a math problem or prompt. 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 the students. In this month’s episode, a six-year-old rising first grader uses a computer simulation to understand addition and subtraction on the number line.

This material is only available to signed-in subscribers.
