As People Get Older, They Get Taller: An Integrated Unit on Measurement, Linear Relationships, and Data Analysis

Elana Joram, Christina Hartman, Paul Trafton 

March 2004, Volume 10, Issue 7, Page 344

Abstract:
A unit of instruction designed to promote algebraic thinking in second graders. Students examined second- and fourth-grade students' ages and heights on a table and graph and described the patterns that they observed in the data. Included are samples of the life-size graphs that students constructed to make predictions about the heights of family members and schoolmates.
