# Ms. Minner's Classroom

A Louisville Middle School Classroom

M.C. Escher, a famous artist, used geometric transformations to create a type of artwork called a tessellation. A tessellation is basically a way of covering a flat surface (plane) with one or more repeated shapes (tiles) with no gaps and no overlaps. The two examples below were created by children. You can see some of Escher’s tessellations in the Transformations Prints Gallery on his official website.

### Monday, March 19

Portions of plans carried over from last week.

Common Core Standards and Extended Standards
8.G.1 Verify experimentally the properties of rotations, reflections, and translations: Lines are taken to lines, and line segments to line segments of the same length. Angles are taken to angles of the same measure. Parallel lines are taken to parallel lines.
8.G.2: Understand that a two dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.
8.G.3: Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.

Student Objectives
I can identify translations, rotations, dilations and reflections.
I can explain the properties of translations, dilations, rotations, and reflections.
I can translate, reflect, and rotate a figure as directed.

Bellwork
Students will complete Math Minute 83.
