High schoolers analyze the vertex form of a parabola and find an approximate fit of a model. They explain the quadratic parabola function and its properties by developing quadratic models. They use translation and dilation to change the general parabola.
Middle schoolers construct a three-dimensional model of a city using both similar and congruent figures and geometric transformations. City must have at least ten buildings with each building labeled and may be constructed out of paper or modeling clay. A two-dimensional representation, drawn to scale, must be included as well.
For 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. 
Here is a study guide on transformations that includes reflections, translations, dilations, and rotations. It also has definitions, helpful diagrams, and several examples involving transformations on the coordinate plane. The lesson could be improved by including more exploration with transformations on the coordinate plane before giving "formulas" to find the coordinates of images.
In this transformations worksheet, 10th graders solve and complete 27 various types of problems that include similar figures and justifying answers. First, they dilate the shape shown using a zoom factor from the origin. Then, students solve for the unknown variable in each similar figure. They also find the perimeter and area of the shaded region of the figure.
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.
Using a TI-nspire calculator, pupils determine the scale factor of a polygon given an image and pre-image.  They also dilate polygons and measure the perimeter and area.  Finally, they determine the ratios of the two figures and compare it with the scale factor. 
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.
Learners create tessellations using patterns. In this geometry lesson, students perform transformation of different polygons and create patterns as they do this.
Tenth graders explore translations, rotations and reflections of two dimensional objects. In this geometry lesson, 10th graders use transformation to move objects and shapes around on a coordinate plane. They create a hands on transformation using constructions paper and graph paper.
Students research the history of the quilt in American History and view a PowerPoint Presentation. They create a quilt square with colored paper using polygons, transformations, rotations, and reflections on the computer and on a coordinate grid.
Students reflect, rotate, translate, and dilate figures in the Cartesian coordinate plane using grid paper and dot paper. They use transformations (i.e., reflections, translations, rotations, and dilations) to describe geometric patterns in the Cartesian plane.
Eighth graders dilate polygons and observe the changes in area and perimeter as the polygon is dilated. They predict the change in the area and perimeter of a polygon given the original size and dilation ratio, and represent it in multiple ways.
Perform transformations on exponential functions! Teach your class how to perform dilation, compression, and translation. They graph exponential functions using the TI Calculator.
Fourth graders create a design that illustrates the reflection concept of geometrical transformation. In this reflections lesson plan, 4th graders use the design to further demonstrate rotations and translations.
Teach your class how to transform a graph! By identifying the domain and range of the functions, high schoolers can observe the parabola and find the vertex of the transformed graph.
Using the TI calculator to visualize and make predictions, learners perform transformation vertically and horizontally on logarithmic graphs in order to solve problems.
Tenth graders explore Cabri Jr.  In this geometry lesson, 10th graders explore the file, drawing, construction, transformation, and display tools of Cabri Jr.  Students explore navigating within an app and how to measure segments, angles, and slopes.
In this dilations and similarity instructional activity, pupils solve 10 different problems that include various dilations. First, they determine the scale factor of dilations found in the illustrated graphs. Then, everyone determines the coordinates of the image of a point under a dilation with the center at the origin of scale factor.
In this translations and dilations worksheet, students sketch the graphs and write equations of graphs for translations and dilations. Students complete 38 questions on this fantastic worksheet.
