Transformations

For Students 8th Standards
Geometry in life-sized dimensions! Using enlarged graph paper, pupils perform a series of transformations. By recording the initial and final placement of the images, they are able to analyze the patterns in the coordinates during a...
Lesson Planet

Symmetry

For Teachers 9th - 11th Standards
Get learners' minds rotating and reflecting while looking for symmetry. Pupils investigate figures to determine the number of lines of symmetry and if the figure has rotational symmetry. Classmates work together in groups to find out the...
Lesson Planet

Transformations

For Teachers 9th - 11th Standards
The coordinate plane is a popular place! Identify rotations, reflections, and dilations on the coordinate plane. Pupils work in small groups to match transformations of a figure with the description of the transformation. They perform...

Mixed Transformations

For Students 8th - 11th Standards
Viewers learn how to identify and perform a variety of transformations with a video that provides seven items on transformations. Pupils demonstrate their understanding of dilations, reflections, rotations, and translations. The video...
Lesson Planet

Enlargements

For Students 8th - 11th Standards
Make enlargements with and without centers. Pupils work through seven problems dealing with dilations or enlargements. The first couple items are strict enlargements without centers, while the others have centers. Class members also...

Reflections

For Students 9th - 11th Standards
Tracing paper is not just for art anymore — pupils can use it to find reflected images, too! Two videos show how to reflect images using tracing paper and find the reflection between the pre-image and image. Learners perform reflections...
Lesson Planet

Rotation

For Students 8th - 10th Standards
Two videos show first how to perform a rotation, given the center, the angle, and the direction of rotations. Individuals then see how to find what the rotation is from one figure to another. Pupils practice doing both in seven problems...

Visualizing Rotations

For Students 8th - 10th Standards
Have classes been going in circles as they study rotations! Math scholars begin with an exploration of rotations using patty paper. As they progress through the lesson, they examine compositions of reflections and their resulting image....
Lesson Planet

Reflections

For Students 8th - 10th Standards
Reflections are the geometric mirror. Pupils explore this concept as they discover the properties of reflections. They focus on the coordinates of the reflections and look for patterns. This is the third lesson in a seven-part series.
Lesson Planet

Translations

For Students 8th - 10th Standards
Use a translation to create a three-dimensional drawing. Scholars first use patty paper to draw translations and then learn how to apply vectors to locate a translation. They use their understanding of the vector translation to draw...
Lesson Planet

An Introduction to Transformations

For Students 8th - 10th Standards
Use geometry to transform learning! This introduction to transformations has pupils use patty paper and rubber bands to create rotations, reflections, translations, and dilations. Individuals learn the vocabulary and notation related to...

Transformations and Isometries

For Students 9th - 12th Standards
Give your class a solid foundational understanding of transformations. The instructor in a concept video describes each type of transformation and transformation notation. He also identifies the types of transformations that are isometries.

An Astronaut in Motion

For Teachers 9th - 12th Standards
How do you model the movement of an astronaut? The activity features software that uses an avatar to mimic movement. Groups work to determine the translation between the pre-image and the image. They then experiment with reflections in...
