Lesson Planet

#### Transformations

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

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

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...

Lesson Planet

#### Mixed Transformations

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

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...

Lesson Planet

#### Reflections

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

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...

Lesson Planet

#### Visualizing Rotations

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

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

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

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...

Lesson Planet

#### Module 7: Modeling with Functions

The sky's the limit of what you create when combining functions! The module begins with a review of transformations of parent functions and then moves to combining different function types using addition, subtraction, and multiplication....

Lesson Planet

#### Transformations and Isometries

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.

Lesson Planet

#### An Astronaut in Motion

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...

#### End-of-Module Assessment Task - Geometry (module 1)

Have you hit a wall when trying to create performance task questions? Several open-ended response questions require a deep level of thinking. Topics include triangle congruence, quadrilaterals, special segments, constructions, and...

EngageNY

#### Review of the Assumptions (part 2)

Is the amount of information getting overwhelming for your geometry classes? Use this strategy as a way to organize information. The resource provides a handout of information studied in relation to triangle congruence. It includes a...

EngageNY

#### Translations

Learn through constructions! Learners examine a translation using constructions and define the translation using a vector. Pupils then construct parallel lines to determine the location of a translated image and use the vector as a guide.

EngageNY

#### Review of the Assumptions (part 1)

What was the property again? Tired of hearing this from your pupils? Use this table to organize properties studied and as a reference tool for individuals. Learners apply each property in the third column of the table to ensure their...

EngageNY

#### Mid-Module Assessment Task - Geometry (Module 1)

How do you prepare class members for the analytical thinking they will need in the real world? An assessment requires the higher order thinking they need to be successful. The module focuses on the concept of rigid transformations...

EngageNY

#### Correspondence and Transformations

Looking for a strategy to organize the information related to transformations? The materials ask pupils to identify a sequence of rigid transformations, identify corresponding angles and sides, and write a congruence statement. They...

EngageNY

#### Applications of Congruence in Terms of Rigid Motions

Corresponding parts, congruent parts, congruent corresponding parts—what does it all mean? The resource challenges pupils to identify corresponding parts for pairs of figures. It uses examples of figures that undergo rigid...

EngageNY

#### Construct and Apply a Sequence of Rigid Motions

Breaking the rules is one thing, proving it is another! Learners expand on their previous understanding of congruence and apply a mathematical definition to transformations. They perform and identify a sequence of transformations and use...

EngageNY

#### Looking More Carefully at Parallel Lines

Can you prove it? Making assumptions in geometry is commonplace. This resource requires mathematicians to prove the parallel line postulate through constructions. Learners construct parallel lines with a 180-degree rotation and then...

EngageNY

#### Characterize Points on a Perpendicular Bisector

Learn transformations through constructions! Pupils use perpendicular bisectors to understand the movement of a reflection and rotation. They discover that the perpendicular bisector(s) determine the line of reflection and the center of...
