Developing Geometric Concepts

Why Geometry?

The resources in this professional development collection were assembled to help you enhance your understanding of geometric concepts via theory, research, and activities that can be adapted for classroom use. If the question “Why Geometry?” is the place to begin, the New Zealand article “Geometry Information” provides key arguments in favor of introducing geometric concepts in the elementary grades.

What Topics are Appropriate?

Some research has investigated how students learn geometric concepts and when they are capable of achieving a deep understanding. The van Hieles worked with individual students and developed their five levels of geometric thought. The IMAGES website details those levels and contains other pages of teaching suggestions and activities to implement them. Jenni Way provides examples of instruction and student work in the van Hiele model. Doug Clements has written extensively on the geometric learning of young children and two of his articles are included.

How Should We Plan to Teach these Topics?

The Annenberg Foundation’s Learner Online has two excellent teacher labs. This collection provides a sampling of topics from the Mathematics Developmental Continuum of the State of Victoria, Australia. In these documents, you will find examples, teaching strategies, activities and progress indicators.

The Educational Development Center has many good resources for teacher professional development. Their article “Right Angle” is one example of how geometric topics can connect with other school subjects.
