If your class has a wide range of proficiency levels, you can pull out students for reteaching, and have more advanced students begin work on the practice exercises. Explain how the coordinates of each point change after the rotation and give examples using different figures.īased on student responses, reteach concepts that students need extra help with. Use the practice problems of the guided notes to introduce graphing figures after rotations about the origin. Emphasize the concept of counterclockwise and clockwise rotations. Walk through the rules for each rotation and discuss the effects of rotating figures. Use the first page of the guided notes to introduce rotations about the origin for 90, 180, and 270 degrees. Refer to the last page of the guided notes for a more detailed example of how rotations are used in jet engines. For example, ask them how rotations are used in video games to move characters or objects. Standards: CCSS 8.G.A.3, CCSS 8.G.A.1, CCSS 8.G.A.2, CCSS 8.G.A.4Īs a hook, ask students why rotations are important in real life applications.They will also have developed their skills in graphing figures on coordinate planes after rotations about the origin, understanding counterclockwise and clockwise rotations, writing rules for transformations when given graphed figures, and writing coordinate points for preimages and images of figures undergoing rotations. This application activity will help students see the relevance and practicality of the topic.īy the end of this lesson, students will have a solid understanding of rotations and how they can be applied in real-life situations. To further connect rotations to real-life situations, students will read and write about the real-life uses of rotations. This hands-on activity will engage students and help them solidify their knowledge of rotations. These notes integrate checks for understanding to ensure students are on the right track.Īfter reviewing the guided notes, students will apply their understanding through a practice worksheet that includes a color by code activity, a maze, and problem sets. The guided notes provide structured information on the rules for rotations about the origin for 90, 180, and 270 degrees, as well as graphing rotations of figures. Through artistic and interactive guided notes, check for understanding questions, a doodle & color by number activity, and a maze worksheet, students will gain a comprehensive understanding of rotations. Examples of this type of transformation are: translations, rotations, and reflections In other transformations, such as dilations, the size of the figure will change. In some transformations, the figure retains its size and only its position is changed. In this lesson plan, students will learn about rotations and their real-life applications. In geometry, a transformation is a way to change the position of a figure. Ever wondered how to teach rotations in an engaging way to your 8th grade geometry students?
