1.11  Geometric Shapes
The student will
a) Identify, trace, describe, and sort plane figures (triangles, squares, rectangles, and circles) according to number of sides, vertices, and angles; and
b) identify and describe representations of circles, squares, rectangles, and triangles in different environments, regardless of orientation, and explain reasoning.
Adopted: 2016
BIG IDEAS
 So I can continue to describe shapes, and objects commonly seen in our lives.
 So that I can see and identify geometric figures that are seen in my class and home, and community (doorknobs, clocks, windows, tables, desks, etc.)
