ab: Summary: The mean can be interpreted as a fair-share value and as a balance
point. Standards documents, including Common Core State Standards for
Mathematics (CCSSM), suggest focusing on both interpretations. In this
article, the authors propose a sequence of five activities to help
students develop these understandings of the mean, and they offer
insights for implementing the activities. They include extensive use of
representations, from concrete to abstract, to scaffold studentsâ€™
experiences and sequence discussions. (ERIC)
