• Resumen

  • This article examines middle school and high school student thinking about the law of large numbers, using a coin toss task. The analysis identifies common justification categories for incorrect responses as well as correct responses. These results are then discussed through the lens of in-school mathematical thinking and out-of-school mathematical thinking.
