# Middle Grades Math: Rotations - Lesson Bundle

by Texas Instruments

Google Form for Paperless Classrooms

The student worksheet has been provided as a Google Form to provide support for the "paperless classroom". Copy the Google Form here. (Note: For more information, visit Google Support). The Google Form brings the student activity to life with the videos embedded. PDF's are also provided in the Download section. For optimal student engagement, have students download the TNS file prior to watching the videos, and then actively engage in the explorations while using the student activity sheet.

#### Objectives

Students will:

• Learn to identify and perform rotations with technology and without technology.
• Explore the relationship between the corresponding parts of the pre-image and image triangles.
• Verify experimentally the properties of rotations with and without a grid.
• Explain how underlying properties relate to rotation.
• Understand the effects that a rotation has upon a triangle by easily manipulating the triangle.
• Discover how to rotate a figure by hand.

#### About the Lesson

This series of video lessons exploring Rotations is designed to be a first exposure to geometric transformations for middle grades or high school. These video explorations are ideal for distance learning, and have been designed so that students can investigate and discover the math quickly while being guided through the exploration.

Extended Explorations (optional):

For an alternative approach to the lesson (without the use of guided videos), download the "Extended Exploration" folder. These files have been designed for students to investigate and discover the math on their own. For optimal results for students using the "Extended Exploration" materials, always have students do the “Tour” activity first – before doing any of the other lessons. The 'Tour' contains information that is needed to understand how to do the other lessons. It is recommended that students follow the sequence of lessons, but once the Tour is completed, the lessons can be done in any order.
