Transformations - 8th Grade Math

This unit focuses on the four transformations in 8th grade math. Students will apply translations, reflections (over x or y-axis), and rotations (90°, 180°, and 270° clockwise or counterclockwise), as well as dilations centered at the origin. Includes lessons investigating transformations, generalizing attributes of congruence and orientation, and writing the algebraic representation to explain the effect of a transformation. Students will create pre-image and 5 subsequent images by applying transformations. The student must also supply a guide in the form of algebraic representations so that others may recreate their work. The student will justify their results through discussion and reflection. The unit as designed covers 15-17 days of a traditional 50 minute period
