Exchange: Geometry in the Middle School: An Exchange of Ideas and Experiences
Geometry and measurement represent two of the nine content strands in the NCTM's Curriculum and Evaluation Standards for School Mathematics (1989) and thirteen of the forty-nine objectives for grades 5-8. In addition, several other content strands have explicit connections to geometry. For example, some of the “patterns and functions” deal with geometric patterns, and some of the probability is in geometric settings. The Standards document describes a vision for the role of geometry and measurement that is different from, and larger than, the traditional role. No longer is it to be a “frills” topic relegated to the back of commonly used textbooks nor restricted to identifying figures and reciting a litany of their properties. Instead, geometry should encompass a variety of experiences in which middle schoolers create their own understanding of the relationships in our multidimensional world. Geometric models should be used to analyze, interpret, and solve problems from probability, algebra, and other areas of mathematics. That is, geometry should take a place among the major topics of emphasis in the mathematics study of a middle school student.
