Math Practice #7 – Look for and Make Use of Structure

Geometry - Standard 2

Classify two-dimensional figures based

on the presence or absence of parallel

or perpendicular lines, or the presence

or absence of angles of a specified

size. Recognize right triangles as a

category, and identify right triangles.

The students in Mrs. Miller’s 4th grade class share the playground shown below. The girls and boys decide to split the playground equally. The boys label their section with the letter B.
