This upper elementary and middle school lesson plan examines the mathematical nature of art, tilings and tessellations. Students will also explore polygons, symmetry, analyze patterns and explore the role of mathematics in nature and our...

Site that focuses on planar pattern and transformations within geometry. It also identifies different kinds of symmetry.

[Free Registration/Login may be required to access all resource tools.] This concept teaches students what rotations are and how to find the coordinates of rotated figures.

An applet is used to explore the rotation symmetry of geometric shapes. [Requires Java.]

An applet is used to investigate the rotation symmetry of regular polygons.

This site helps give the definition of what an n-fold rotation is. Also discusses other discontinuous groups of rotation and translation in the plane.

An introductory look at the interactive Geometer's Sketchpad in terms of using it to explore rotations, translations, and reflections. Only a beginner's amount of skill with the program is needed. Exploration questions are given for the...

This StudyCards stack tests students' understanding of translation, transformation, symmetry, dilation, and rotation of a point to form images. Teachers require TI StudyCards Creator Software and students will need the StudyCardApp on...

Dr. Math, in a reply to a student question, shows how to derive the equation of a parabola for situations when the line of symmetry is not || to one of the axes.

Test your knowledge of rotational symmetry.

Get independent practice working with scientific and standard notation. Each incorrect response gets a text box explanation and another try. Correct responses are confirmed.

In this tea store, the boxes all have different shapes! What do you know about shapes?

Based off of the hit television show NUMB3RS, this lesson has students examine a set of transformations to determine if certain properties (such as associativity and closure) exist for equilateral triangles. Students create tables of...

In Spanish. In this unit you can learn about movements in the plane: translations, symmetry and rotation.

In this task, seven pennies are placed in a circle so that they are all touching one in the center and their neighbors. Learners are asked to find as many rigid motions of the plane as they can which are symmetries of this configuration...

What lowercase letters read the same both upside down and right side up? If you have the answer, then you can handle this geometric symmetry math challenge. A one-page activity from the NTCM Math Challenge for Families collection....

In this instructional activity, students observe symmetry, geometric shapes, and angles in two Early American dances, and then choreograph their own dance with symmetrical figures. Media and teaching materials are included.

This site presents information on the three basic transformations of figures in a plane: Reflections, Rotations, and Translations.

For students who have ever played dominoes and Tetris, polyominoes will strike them as a great deal of fun. Teachers will see the educational benefits of working with similar and congruent shapes and rotating them in a plane. Exploration...

This site is for the purpose of using proofs for geometry. It helps by giving some useful theorems.

Given geometric figures on the coordinate plane, the student will apply the definition of congruence, in terms of rigid transformations, to identify congruent figures. The student will also identify and distinguish between reflectional...

Students show comprehension of advanced mathematics skills in Geometry. The questions check understanding on transformational geometry. Topics include translations, symmetry, and rotations.

A unique geometry project that asks students to complete a transformation using a picture. Project includes instructions, examples, and quiz questions.
