4.G.2
2011
Domain: Geometry
Cluster: Draw and identify lines and angles, and classify shapes by properties of their lines and angles.
Standards: 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.
Essential Questions
-How do you classify a
two-dimensional figure?
Content Statements
- Students will learn to
identify polygons.
- Students will learn to
identify and classify
triangles
- Students will learn to
identify quadrilaterals
- Students will solve
problems by making and
testing generalizations.

Enduring Understandings
- Two- dimensional or plane
shapes have many properties that
make them different from one
another. Polygons can be
described and classified by their
sides and angles.
- Two-dimensional or plane
shapes have many properties that
make them different from one
another. Polygons can be
described and classified by their
sides and angles.
- Two-dimensional or plane
shapes have many properties that
make them different from one
another. Polygons can be
described and classified by their
sides.
- Commonalities in attributes of
objects or situations can be found
and used to make generalizations
about relationships
Activities, Investigation, and Student Experiences
Students will sort two-dimensional figures based on parallelism,
perpendicularity, and angle types using a Venn Diagram.
Students will draw quadrilaterals with diagonals. Students will
investigate parallel or perpendicular lines and right triangles.
Given specified criteria students will draw the figure. (example:
a parallelogram with one right angle; a quadrilateral with one
pair of parallel sides.)
