Exploring Quadratic Data With Transformation Graphing
Students investigate the concept of transformations with the help of a graphing calculator from Texas Instruments. They participate in a variety of activities made with specific instructions for this type of calculator. The lesson is a description of a larger unit.
Transformations, Tessellations, and Technology
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.
Students 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.
Unit 14 - Loci and Transformations
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.
What is a Transformation?
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.
Defining Transformations that Create Congruent Figures
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.
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.
Learners examine images and preimages of a mapping and identify isometry. They view images by M.C. Escher, observe teacher demonstrations, and create a translation image, a rotation image, and a dilation.
Tenth graders investigate dilations. In this geometry lesson plan students explore dilations on a coordinate plane as they examine the coordinates of the preimage and the image.
Exploring Quadratic Data with Transformation Graphing
Using a data collection device to collect data regarding a bouncing ball, young scholars 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.
Exploring Quadratic Data : Transformation Graphing
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.
Dilation on a Coordinate Plane
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.
Knowing My Transformations
Sixth graders explore geometric transformations of two-dimensional shapes. They predict the size, position or orientation of two dimensional figures before performing a transformation.
Transformations and Tessellations
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.
Investigate the Rigid Motions of Reflection, Rotation, Translation, and Dilation
Young scholars investigate the rigid motions of reflection, rotation, translation, and dilation. This investigation be accomplished through classroom instruction and exploration using Geometer's Sketchpad.
Transformational Geometry Using the Geometer's Sketchpad
Students 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.
If it is not motion, what is it? (Geometric Transformations)
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.
Transformations with Circles and Ellipses
Students 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.
Transformations with Circles and Ellipses
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.
Introduction To Transformations Lesson
High schoolers 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.
