#### 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...
