Learners investigate properties of similar figures. In this properties of similar figures lesson, pupils construct similar figures using Cabri Jr. They dilate their figure to create a similar one, and discuss the relationships between the angle measures and side lengths of the two similar figures.
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.
Perform transformations on exponential functions! Teach your class how to perform dilation, compression, and translation. They graph exponential functions using the TI Calculator.
Teach your class how to transform a graph! By identifying the domain and range of the functions, students can observe the parabola and find the vertex of the transformed graph.
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.
Using the TI calculator to visualize and make predictions, high schoolers perform transformation vertically and horizontally on logarithmic graphs in order to solve problems.
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.
Young scholars 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.
High schoolers perform dilation on various geometric shapes. They also discuss pros and cons of dilation and employ the Frayer Model to study the vocabulary words in this section.
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.
In this dilations and similarity worksheet, 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.
In this geometry worksheet, 10th graders solve questions that involve rotations, reflections, and dilations.  The one page worksheet contains ten multiple choice questions.  Answers are not provided. 
The concept of transformation is explored as students use their Ti-Nspire to transform polygons. Students translate, reflect, and rotate various polygons and construct tessellations.
In this dilations of basic functions activity, students graph given functions. They explore the transformation and dilation of the function. This two-page activity contains 8 multi-step problems.
Tenth graders define transformation and identify the image and pre-image. For this geometry lesson, 10th graders create their own shapes and transform it on a coordinate plane to create a reflection, rotation, dilation and translation. They come up with their own designs or cut them out of a magazine.
For this transformations and conditional statements review worksheets, students answer 14 questions that involve writing conditional statements, sketching and identifying transformations, and a mixed review on angles and angle bisectors.
Students dilate different objects. In this geometry lesson, students reduce and enlarge objects using dilation. They relate dilation to the real world.
There are four activities in this extensive lesson covering the identity matrix and scaling, the linear representation of translations, the linear representation of rotations, and reflections. In small groups, they use the Cabri II computer program to move objects and make observations. In their groups, they discuss, solve and answer worksheet questions for each activity.
