Students complete a unit about transformations and tessellations. They explore various tessellation websites, determine which shapes tessellate, complete a log about which website activities they complete, and create a tessellation using a computer Paint program.
Young scholars explore what happens when geometric figures are transformed on the coordinate plane. They work in pairs, moving geometric shapes in the plane, and formalize their rules as functions.
In this transformations worksheet, 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.
Sixth graders explore geometric transformations of two-dimensional shapes. They predict the size, position or orientation of two dimensional figures before performing a transformation.
Shape shifters explore transformation through the construction of patterns on a TI handheld. In this math lesson, learners investigate and apply their knowledge of reflection, translation, rotation, and dilation. This assignment requires minimal teacher involvement.  
Students investigate the rigid motions of reflection, rotation, translation, and dilation. This investigation be accomplished through classroom instruction and exploration using Geometer's Sketchpad.
Learners complete a webquest on the various types of symmetry. Using a computer, they explore the concepts of transformational geometry and identify points, segments, lines and planes. They experiment with the rotation of a quadrilateral and create pinwheels.
Students perform transformation and rotations on different polygons. In this geometry instructional activity, students continue their research in global warming as they discuss rotation and transformation of axis of the globe. They apply properties of geometry to solve cross curricular questions.
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.
Pupils perform transformations on circles and ellipses. In this algebra lesson, students rotate, reflect, translate and dilate circles and ellipses. They analyze a given graph and write an equation for that graph.
Students use problem solving skills to rotate, reflect, translate, and dilate a given ellipse and circle. Students graph their circles and ellipses and practice writing and solving equations based on their graphs.
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.
Creativity is endless when your mathematicians take a simple image and use transformations to create their own poster inspired by geometry. While certain rotations and reflections are required, learners will be able to create ten new images by flipping, moving, spinning, and zooming their original using Word. Your artists will create clues on how they came to the new image and see if other classmates can figure out which image belongs with that clue. A fun activity that practices transformation vocabulary and incorporates a computer-based assignment.
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.
Learners perform transformation, rotation and reflection on functions. In 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.
Here is a instructional activity that starts out with learners creating congruent figures by drawing the exact same polygon as their partner. From here, they have a discussion about why what they drew is an exact copy, followed by other activities that look at different shapes, some with transformations, to determine their congruence.   
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.
In this geometry worksheet, students dilate a quadrilateral by first determining the points, applying the scale factor, and redrawing the transformed image. There is 1 shape to transform.
Rotations, reflections, and translations are explored as geometers rotate through three different stations and develop their own definitions for these terms. Afterward, they work in small groups to classify different figures based on their definitions.
Using a data collection device to collect data regarding a bouncing ball, students use various features on graphing calculators to experiment with the parameters of the vertex form of the parabola and their effect on the shape of the curve. They use this concept to find a quadratic model. They also use translation and dilation to change the general parabola.
