Rotations in the Coordinate Plane - Lesson Plan Volume 26
This lesson uses the X-Y Coordinate Geoboard to examine and investigate rotations of 90, 180, and 270. Students will be asked to create a particular figure in a given quadrant and then rotate it around the origin (0, 0) into various other quadrants. Students will begin to see the correlation of coordinates as they work on a variety of rotations. Figures for this activity include triangles and quadrilaterals.
Before introducing this lesson to students, it is important that students have a firm grasp of translation and reflections. It is recommended that you complete Nasco MathWorks Volume 25: Translations and Reflections lesson plan, U27682, prior to tackling this one. In that lesson, not only did students gain a firm understanding of translations and reflections, but they also familiarized themselves with coordinate plane terms such as quadrants and axes.
Students will be able to…
- Analyze how x-y coordinates change through various steps in rotations.
- Compare different degrees of rotations.
- Conclude that each type of rotation follows a given set of rules.
