Geometry Sites for Elementary Teachers
This website contains information and resources that are designed to help teachers develop a deeper understanding of geometry and measurement concepts and to assist in designing meaningful instruction for elementary students.
There are about 60 prints in this gallery maintained by David McAllister.
