Week #6
Unit of InstructionFocus 6: Transformations
Standard(s) Taught

MAFS.8.G.1.3: Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.

MAFS.8.G.1.4: Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them.

Learning Targets and Learning Criteria

describe the changes occurring to x- and y- coordinates of a figure after a translation, reflection, rotation, or dilation. • reason that a 2-D figure is congruent to another if the second can be obtained by a sequence of rotations, reflections, translation. • describe the sequence of rotations, reflections, translations that exhibits the congruence between 2-D figures using words

explain how transformations can be used to prove that two figures are similar. • describe a sequence of transformations to prove or disprove that two given figures are similar. • know the definition of similar and why dilation alone is not enough to determine similarity.
