He then makes the grid according to the key features of the picture, so that a point at (2, 0) is. The coordinate plane is positioned so that the x axis separates the image from the reflection. He places a coordinate plane over the picture. Tyler takes a picture of an item and its reflection. 1In typical parlance, a rotation refers to a proper rotation. Translations, Rotations, and Reflections. The ideas on this foldable are largely hers, I just manipulated them a little bit to fit my class. Namely, curl the fingers of your right hand around. The two template files are also attached for your use. I'm including pictures of the completed foldable (It's on plain white paper. When describing the direction of rotation, we use the terms clockwise and counter clockwise. Rotations can be described in terms of degrees (E.g., 90° turn and 180° turn) or fractions (E.g., 1/4 turn and 1/2 turn). For me, that meant putting more of a focus on developing rules for translations and viewing translations as more a function with an input and output. When describing a rotation, we must include the amount of rotation, the direction of turn and the center of rotation. I wanted to take her ideas and turn them into a foldable more geared toward high school geometry. Her INB page is geared toward 8th grade CCSS standards. I was browsing it and noticed some really awesome interactive notebook pages for transformations. I've read (and drooled over) Jessie Hester's blog before. If you walk into my classroom, it usually looks like colored paper and markers were scattered about by small tornadoes that most people call high school students. If you know me, you know I teach geometry with foldables. Our state exam (Quality Core) just doesn't put much emphasis on it, but I've decided to expand the time I dedicate to them, in keeping with CCSS. Use a protractor to measure the specified angle counterclockwise. I wrote a set of statistics lesson for LearnZillion, and now I'm re-writing my transformations unit for my geometry classes. The amount of rotation is called the angle of rotation and it is measured in degrees. A rotation is an example of a transformation where a figure is rotated about a specific point (called the center of rotation), a certain number of degrees. In geometry, a transformation is an operation that moves, flips, or changes a shape to create a new shape. I've been doing a lot of work this summer writing curriculum. Write the mapping rule for the rotation of Image A to Image B.
