# Transformations and Symmetry

## Transformations and Technology: What Path to Follow?

This article describes a technology-based approach for dealing with a misconception that some students hold concerning the equivalency of geometric transformations. The article looks at students studying transformations as mathematical entities and not just as procedures to apply to shapes. Students use technology-based activities to help rectify commonly held misconceptions. This resource would be a good supplement for sections II and IV.

## Space and Shape in Geometry

This is an online resource that provides teachers with a rationale for the content topics, activities with supporting background, additional connections to the standards, other related resources as well as connections across grade spans. A good resource to supplement the readings from sections I, II and III.

## Research Ideas for the Classroom: High School Mathematics: pages 140-152

Research Ideas for the Classroom is a three-volume series of research interpretations for early childhood, middle grades, and high school mathematics classrooms. Sections can be used as supplements for Section IV.
