Title: Using Exploration and Discovery To Determine the Vertices of Transformed Images
Description:
This handson lesson uses exploration and discovery to help students determine the coordinates of the vertices of various figures when translated, rotated, or reflected in a coordinate plane. The exploration phase will access students' prior knowledge and prepare them for the assigned task of using and applying their understanding of transformed images to new situations. The final project will be a cooperative activity, requiring collaboration in the application phase to discover the patterns and create graphs following directions unique to each group.
Standard(s): [MA2013] (8) 18: Describe the effect of dilations, translations, rotations, and reflections on twodimensional figures using coordinates. [8G3]
Subject: Mathematics (8)

Title: Geometric Quilts
Description:
Students will use a square to investigate other polygonal shapes that can be formed. Students will work with these polygons to make designs that will later constitute cooperatively designed quilts. The quilts will be made by translating, rotating, or reflecting a thirtysix patch design. The completed quilts will then be used for a discussion of area and perimeter. Students will blog about what they have learned while doing the lesson and will include pictures of their finished product in our class blog.
Standard(s): [MA2013] GEO (912) 34: Determine areas and perimeters of regular polygons, including inscribed or circumscribed polygons, given the coordinates of vertices or other characteristics. (Alabama)

Title: Commutative Rectangle
Description:
In this lesson, one of a multipart unit from Illuminations, students investigate the concepts of identity, inverse, commutativity, and associativity using a geometric model. Moves are performed with a rectangle, and the results of an operation that combines two moves are analyzed.

Title: Understanding Congruence, Similarity, and Symmetry Using Transformations and Interactive Figures: Visualizing Transformations
Description:
The interactive figures in this fourpart example from Illuminations allow a user to manipulate a shape and observe its behavior under a particular transformation or composition of transformations. eMath Investigations are selected eexamples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The eexamples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the eexamples are natural companions to the iMath investigations.
