Mirror Symmetry/Mirror Images
Students explore lines of symmetry in geometric shapes. In this geometry lesson, students construct angles using mirrors and rubberbands, then predict the number of images that will appear in the reflection. Students reproduce lines of...

Reflections
Reflections are the geometric mirror. Pupils explore this concept as they discover the properties of reflections. They focus on the coordinates of the reflections and look for patterns. This is the third lesson in a seven-part series.

Geometric Sequences and Exponential Functions: Bouncing Ball
Explore a geometric sequence model through a simulation. Learners change the starting drop height of a ball and watch how the heights of following bounces change. They consider the ratio of the consecutive bounces as they analyze...

Properties of Reflections
Students perform transformation on their polygons. In this geometry instructional activity, students identify the correct transformation of each shape. They move the polygons around on a coordinate plane. There are extension and homework...

An Introductions to Congruent Polygons
Students differentiate between similar and congruent polygons. In this geometry lesson, students define the theorems and reasons for polygons similarity and congruence. They are given pictures and patterns to differentiate and identify.
