See how geometry software expresses geometric shape reflections.

Students are introduced to translations, reflections, and rotations and how to explore them in real-world scenarios.

The goal of this task is to compare and contrast the visual intuition we have of reflections with their technical mathematical definition. Aligns with G-CO.A.4.

Mirror Image by Canadian author K. L. Denman is about the perceptions two teenage girls have of each other and how this changes as they get to know and appreciate one another.

By the end of the activity students will be able to identify a given function reflection, identify the way the graph will change and sketch a graph of the reflected function.

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

Given two figures on the coordinate plane, draw the line of reflection that takes one figure to another.

This PBS site provides a transcript of and interview from 'The Newshour with Jim Lehrer' in which Shelley Fisher Fishkin, the author of a book about Twain, discusses Twain's cultural contribution as well as the way that the criticisms of...

This is the last chapter of a biography of Washington which was written only eight years after his death by David Ramsay, a man who had known Washington personally, and who had been "an active player in the momentous events of America's...

Information for those affected by eating disorders, namely anorexia nervosa, bulimia and binge-eating, depression, obsessive-compulsive disorder and self-injury.

Suppose ABCD is a quadrilateral for which there is exactly one rotation, through an angle larger than 0 degrees and less than 360 degrees, which maps it to itself. Further, no reflections map ABCD to itself. What shape is ABCD? Aligns...

In this task, 8th graders are presented with several rectangles that have diagonal lines through them and are placed on grids. They are asked to draw reflections and to discuss rectangles that are squares. Aligns with 8.G.A.

Students will understand all transformations of functions: translations, dilations and reflections. By the end of the activity students will be able to identify a function transformation, identify the way the graph will change given a...

A discussion of the acoustical features of a room and their effects upon the perception of sound. Topics such as absorption, reflection, and reverberation are clearly discussed and cleverly illustrated.

Given rotations, reflections, translations, and dilations, students will be able to develop algebraic representations for rotations, and generalize and then compare and contrast the properties of congruence transformations and...

In this extremely detailed unit, learners will learn the about innate and learned characteristics in animals and humans through a series of teacher and student-led discussions, readings, reflections, learning activities, and...

This task applies reflections to a regular hexagon to construct a pattern of six hexagons enclosing a seventh. The focus of the task is on using the properties of reflections to deduce this seven-hexagon pattern. Aligns with G-CO.B.6.

In this instructional activity, The Black-Eyed Peas song entitled "Where is the Love?" will be dissected by students. Then students will build upon the song's them and compare it with the picture book by Denise Fleming, Where Once There...

Putt-Putt golf can be a great tool in helping students understand angles and their reflections. Here a teacher demonstrates the "Course," set up in his classroom to assist in explaining to students how to use geometry and angles in...

This site gives some examples of line reflection transformations. Includes coordinate graphs to show reflections of lines and shapes.

This lesson focuses on rigid transformations, a specific set of rules that convert one geometric figure into another one. There are many different types of transformations, like reflections or rotations. It provides several practice...

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,...

Eighth graders are shown two line segments that are the same length and must describe a sequence of reflections that exhibits a congruence between them. Aligns with 8.G.A.2.

"Victory at Paradise Hill" is a book by author William Roy Brownridge. The story follows the trials of two brothers who aren't able to play hockey. This teacher's guide includes author information and reflections about how the book...
