See how geometry software expresses geometric shape reflections.

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.

This task examines some of the properties of reflections of the plane which preserve an equilateral triangle. The task gives learners a chance to see the impact of these reflections on an explicit object and to see that the reflections...

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.

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

Investigate the behavior of light that is reflected off a spherical mirrored surface.

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...

This task uses GeoGebra software, which can be freely downloaded, to explore what happens to the line segments and angles of a triangle when it is reflected, rotated, and translated. Includes printable task sheet for students and a...

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

Students will understand the concept of the ray model of light and how light interacts with matter and reflections.

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.

Build your own polygon and transform it in the Cartesian coordinate system. Experiment with reflections across any line, rotations about any point, and translations in any direction.

This hypertext physics course tutorial on nonfocusing surfaces relates various design principles to good auditorium design. Illustrated.

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.

This site from Science U gives a good example of reflection of symmetry. It also gives some background information about reflection as well.

Workshop 8 takes viewers into the classrooms of three language arts teachers-Velvet McReynolds, Mary Cathryn Ricker, and Jack Wilde-as their students tackle the ongoing task of revision. Throughout the workshop, we hear reflections on...

This lesson focuses on wallpaper groups. While there are infinitely many possible patterns, they all have one of just 17 different symmetry groups. These are called the Wallpaper Groups. Every wallpaper group is defined by a combination...

The purpose of this task is to explore reflections in the context of paper folding. Each fold is associated with a line of reflection and understanding each step in the construction requires careful analysis of angles and of the...

This article discusses teaching vocational work ethics using various methods. Author includes notes on key concepts, the background, design, setting, subjects, findings, reflections, and conclusions of the study.

This site contains a list of 10 words from an interview with the author Beverly Cleary who discussed reflections about her life and written works. Teachers can digitally assign this list to their students to reinforce the spellings,...

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

Reflect any point, line segment, triangle, or any other figure over one or two lines using this dynamic applet. Points and lines are entered by point-and-click rather than by typing equations or ordered pairs. A very neat exercise to...

Find a clear explanation of similar figures. Discusses how they can be transformed through a sequence of rotations, reflections, translations, and dilations. Explanations are supported with illustrated examples.

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...
