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
Students 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.
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.
Perform transformations on exponential functions! Teach your class how to perform dilation, compression, and translation. They graph exponential functions using the TI Calculator.
Graphic Designing with Transformed Functions
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.
In this transformations instructional activity, 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.
Using the TI calculator to visualize and make predictions, learners perform transformation vertically and horizontally on logarithmic graphs in order to solve problems.
The Bigger, The Better? Part 2 (Dilations)
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.
Discovering Math: Exploring Geometry
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.
Transformations on the Coordinate Plane
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.
Geometry - Scale Factor
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.
Getting Started with Geometry - Scale Factor
High schoolers explore the concept of scale factors. In this scale factors instructional activity, students dilate polygons and determine the ratio of the perimeters and areas of an image and pre-image. High schoolers use Ti-Nspires to graph triangles, measure angles, and determine the ratios of images and pre-images.
How do you keep track of a melting iceberg?
Students investigate transformation as it relates to functions and relations. In this geometry instructional activity, students calculate the rate of a melting iceberg using functions and graphing.
Students create tessellations using patterns. In this geometry lesson, students perform transformation of different polygons and create patterns as they do this.
Translations, Reflections, Rotations
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.
Translations and Dilations
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.
Dilations and Similarity
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.
Transformations and Tessellations
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 worksheet, students answer 11 questions that involve finding lengths given the scale factor, determining transformation size, finding the scale factor, and graphing dilations.
Dilations of Basic Functions
In this dilations of basic functions worksheet, students graph given functions. They explore the transformation and dilation of the function. This two-page worksheet contains 8 multi-step problems.
