Embedded Files
In 8th grade, students analyze, create and represent linear and simple non-linear functions in multiple ways to make connections between them, including mathematical concepts related to bivariate data and Pythagorean Theorem, and “real-world” situations like those arising from two & three dimensional space.
The Story of Math 8 - Unit 7: Transformations, Congruence & Similarity
(Up to 20 days)
The big ideas of this unit are congruence & similarity, which are explored in the context of rigid transformations and dilations, respectively. Rigid transformations include translations, reflections & rotations. Students should be able to identify and construct each, and they should be able to use and describe a sequence of any rigid transformation to determine or exhibit congruence. Likewise, students should be able to identify and construct a dilation, and they should be able to use and describe a sequence of any transformation to determine or exhibit similarity. Depth can either be embedded or included later, time permitting, by being sure students understand and can describe transformations with and without coordinates. In addition, students can verify experimentally the properties of transformations for further depth.
