9th - 12th

Students explore the concept of transformations. In this transformations lesson, students enter data into lists and make a scatter plot of points. Students use lists to transform the data points by shifting the points, left and right, or up and down. Students also enlarge and shrink the data points.

#### Understanding the Properties of a Dilation

9th - 12th

In this dilations learning exercise, students solve 29 short answer and graphing problems. Students graph ordered pairs to construct polygons. Students dilate their constructions and see how the image and pre-image are related.

#### Unit 14 - Loci and Transformations

9th - 12th

In this transformations activity, students solve 25 short answer problems. Students dilate, reflect, and translate points and figures in the coordinate plane. Students determine scale factors and lines of symmetry of figures.

#### Transformations and Tessellations

8th - 10th

Shape shifters explore transformation through the construction of patterns on a TI handheld. In this math lesson, students investigate and apply their knowledge of reflection, translation, rotation, and dilation. This assignment requires minimal teacher involvement.

#### Introduction To Transformations Lesson

9th - 12th

Students investigate the concept of transformations and how they are used in various types of problems and define the terms of rotation, reflection, translation, and dilation. They practice using the GSP technology to apply practices to display the images in two or three dimensional space.

#### Transformational Geometry

9th - 10th

Students work in cooperative groups to manipulate a figure on the computer to demonstrate different types of geometric transformations. They generate formulas that can be used to translate different figures.

#### Transformation of Functions

9th - 11th

Students perform transformation, rotation and reflection on functions. For this algebra lesson, students identify different parts of a graph and how it affects the transformation. They find the domain and range of each function.

#### The Bigger, The Better? Part 2 (Dilations)

9th - 10th

Students resize figures using scale and dilations. In this geometry lesson, students dilate shapes using a coordinate plane. They complete a handout that goes with this lesson, and review previous knowledge as well.

#### Dilation on a Coordinate Plane

9th - 12th

For this geometry worksheet, learners dilate a quadrilateral by first determining the points, applying the scale factor, and redrawing the transformed image. There is 1 shape to transform.

#### What is a Transformation?

6th - 12th

A transformation is the process of changing the graph of a figure or a shape. The instructor introduces the four most common transformations: reflection, dilation, rotation, and translation. So watch as she draws the transformations on a graph.

#### Computer Animation

10th - Higher Ed

In this translation lesson, explore through the use of matrix multiplication to rotate, reflect, dilate and translate images. Discussion of dilation, rotation, symmetry, and motion of objects are all covered in this insightful lesson.

#### Discovering Math: Exploring Geometry

6th - 8th

Apply geometric properties and formulae for surface area and volume by constructing a three-dimensional model of a city. Learners use similar and congruent figures and transformations to create a city of at least 10 buildings. They trade with classmates, who calculate surface area and volume of some of the structures. Refers to a Discovery Education video/DVD to support and enrich the project; a link takes you to a website to order it. Charts mentioned are not attached.

#### Getting Started with Geometry - Scale Factor

9th - 12th

Students explore the concept of scale factors. In this scale factors lesson, students dilate polygons and determine the ratio of the perimeters and areas of an image and pre-image. Students use Ti-Nspires to graph triangles, measure angles, and determine the ratios of images and pre-images.

#### Transform Your Geometry into a Work of Art

9th - 10th

Mathematicians utilize artwork to help illustrate the major ideas of transformations and tessellations. They visually identify transformations including reflections, rotations, and translations. They discuss how artists have used geometry in their artwork.
