The first half of the 19th century saw the emergence of many social and religious movements. Read about the Second Great Awakening and how it related to and changed the practice of and participation in religious life. See also how it...

This one page website can expand your logic, Motion Geometry and pattern recognition knowledge. The solution is available to double check your answers.

Resources to supplement classroom instruction of transformations and reflection. Lesson pages offer definitions and examples of composition of transformations and glide reflections. A practice page has a nine-question quiz. There are...

[Free Registration/Login Required] A comprehensive lesson plan for teaching how to prove that all circles are similar by using three types of transformations.

This lesson plan reviews transformations in the coordinate plane while mimicking real-world planning skills. It gives an assessment and ideas for remediation, extention as well as ways to manage behavior problems and reluctant learners.

[Free Registration/Login may be required to access all resource tools.] Recognizing and identifying rotation transformations and rotational symmetry

Analyze various shapes according to their reflective and rotational symmetries. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This lesson focuses on symmetry including reflectional symmetry, rotational symmetry, and palindromes. It defines each, gives examples, and practice activities.

Definition of congruent. Choose the "here's more" link to see examples of a rotation, reflection and translation.

[Free Registration/Login may be required to access all resource tools.] Reflect a figure.

Find the reflection that maps a given figure to another and draw the image of a reflection. The lines of reflection in this exercise have a wide range of slopes.

The goal of this task is to use the unit circle and rigid transformations in order to establish some fundamental trigonometric function identities. Aligns with F-TF.A.2 and F-TF.A.4.

From entertainment devices to lifesaving medical technologies, Latino inventors have advanced humankind through their contributions. Latino inventors have created revolutionary devices that have transformed our everyday world - and often...

When you witness an injustice, remaining silent or acting as a bystander is an active choice that is an impediment to justice. In this activity students will have the opportunity to examine the consequences of remaining silent...

This Regents Prep site contains numerous problems concerning line reflections. Each multiple choice problem contains a short explanation.

Examine the result of reflecting a shape successively through two different lines.

This upper elementary and middle school lesson plan introduces a variety of motion geometry concepts such as translations, reflections, and rotations. Lots of interactive support for students.

Students learn how to sketch a shifted and scaled function. Topics explored include horizontal scaling, vertical scaling, horizontal reflections, and vertical reflections. Class notes, examples, and practice problems are used to...

A rigid motion of the plane is a map of the plane to itself which preserves distances between points. The purpose of this task is to use fixed points as a tool for studying and classifying rigid motions of the plane, i.e., translations,...

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

In this activity, students describe how to move a shape from one place to another in a plane. They learn about translations, rotations, and line reflections. [Requires Adobe Reader.]

A succinct test for assessing geometry concepts. Assessment is scored online giving immediate feedback. An excellent assessment tool.

Students explore slides, flips, and turns in this interactive web lesson.
