Mathematical Models with Applications: Two-Point Perspective Drawing
ORC# 5825
Resource Information
Resource Type: Lessons
Discipline: Mathematics
Professional Commentary: Students use interactive geometry exploration software (GES) to create a two-point perspective drawing. Students explore geometric transformations of the model of a rectangular prism viewed from different perspectives....

Symmetries II
ORC# 2408
Resource Information
Resource Type: Lessons
Discipline: Mathematics
Professional Commentary: Many objects in nature--butterflies, flowers, crystals, etc.--and many objects we use every day have reflection symmetry. In this four-part investigation using JavaSketchpad applets, students learn the mathematical definitions and properties of reflections and reflection symmetry....

Symmetries I
ORC# 2407
Resource Information
Resource Type: Lessons
Discipline: Mathematics
Professional Commentary: Fix a center, turn, and you have a rotation. Many objects in nature--flowers, starfish, crystals, etc.--and many objects we use every day have rotational symmetry....

Straight Lines in 3-Space
ORC# 9787
Resource Information
Resource Type: Content Supports
Discipline: Mathematics
Professional Commentary: This applet features five 3-D diagrams, each of a line in coordinate space. Each diagram can be rotated to show the line in reference to all planes in an x-y-z system....

"As the World Turns"
ORC# 8877
Resource Information
Resource Type: Content Supports -- Technologies
Discipline: Mathematics
Professional Commentary: This resource is not really a lesson, but it provides a step-by-step introduction to graphing polygons on Geometer's Sketchpad&reg; and performing simple translations, rotations, and reflections. This site could be good preparation for a more substantive lesson on transformations....

Understanding Congruence, Similarity, and Symmetry Using Transformations and Interactive Figures: Composing Transformations
ORC# 1456
Resource Information
Resource Type: Content Supports -- Technologies
Discipline: Mathematics
Professional Commentary: Translations (slides), reflections (flips), and rotations (turns) are geometric transformations that change an object's position or orientation but not its size or shape. The applet in this last of four activities (all accessible from this site) allows students to manipulate a figure and observe its behavior under various compositions of transformations....
