2Dimensional Figures
5th Grade


Alabama Course of Study Standards:
23

Explain that attributes belonging to a category of twodimensional figures also belong to all subcategories
of that category.Example: All rectangles have four right angles, and squares have four right angles, so squares are
rectangles. 
Arkansas Academic Standards:
5.G.B.3

Understand that attributes belonging to a category of twodimensional figures also belong to all subcategories of that category
For example: All rectangles have four right angles and squares are rectangles, so all squares have four right angles. All isosceles triangles have at least two sides congruent and equilateral triangles are isosceles. Therefore, equilateral triangles have at least two congruent sides. 
Arizona  K12 Academic Standards:
5.G.B.3

Understand that attributes belonging to a category of twodimensional figures also belong to all subcategories of that category. 
Common Core State Standards:
Math.5.G.3 or 5.G.B.3
Georgia Standards of Excellence (GSE):
MGSE5.G.3

Understand that attributes belonging to a category of twodimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles. 
North Carolina  Standard Course of Study:
5.G.3

Classify quadrilaterals into categories based on their properties. Explain that attributes belonging to a category of quadrilaterals also belong to all subcategories of that category.
 Classify quadrilaterals in a hierarchy based on properties.

New York State Next Generation Learning Standards:
5.G.3

Understand that attributes belonging to a category of twodimensional figures also belong to all subcategories of that category. e.g., All rectangles have four right angles and squares are rectangles, so all squares have four right angles. Note: The inclusive definition of a trapezoid will be utilized, which
defines a trapezoid as "A quadrilateral with at least one pair of parallel sides." 
Ohio's Learning Standards:
5.G.3

Identify and describe commonalities and differences between
types of triangles based on angle measures (equiangular, right, acute,
and obtuse triangles) and side lengths (isosceles, equilateral, and
scalene triangles). 
Wisconsin Academic Standards:
5.G.B.3

Understand that attributes belonging to a category of twodimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles. 
Alabama Course of Study Standards:
22

Classify quadrilaterals in a hierarchy based on properties. 
Arkansas Academic Standards:
5.G.B.4

Classify twodimensional figures in a hierarchy based on properties
Note: Trapezoids will be defined to be a quadrilateral with at least one pair of opposite sides parallel, therefore all parallelograms are trapezoids. 
Common Core State Standards:
Math.5.G.4 or 5.G.B.4

Classify twodimensional figures in a hierarchy based on properties. 
Georgia Standards of Excellence (GSE):
MGSE5.G.4

Classify twodimensional figures in a hierarchy based on properties (polygons, triangles,
and quadrilaterals). 
Louisiana Academic Standards:
5.G.B.4

Classify quadrilaterals in a hierarchy based on properties. (Students will define a trapezoid as a quadrilateral with at least one pair of parallel sides.) 
Massachusetts Curriculum Frameworks:
5.G.B.4

Classify twodimensional figures in a hierarchy based on properties. For example, all rectangles are parallelograms because they are all quadrilaterals with two pairs of opposite sides parallel. 
Ohio's Learning Standards:
5.G.4

Identify and describe commonalities and differences between
types of quadrilaterals based on angle measures, side lengths, and
the presence or absence of parallel and perpendicular lines, e.g.,
squares, rectangles, parallelograms, trapezoids, and rhombuses. 
Tennessee Academic Standards:
5.G.B.3

Classify twodimensional figures in a hierarchy based on properties. Understand that attributes belonging to a category of twodimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles. 
Pennsylvania Core Standards:
CC.2.3.5.A.2

Classify twodimensional figures into categories based on an understanding of their properties. 
Pennsylvania Core Standards:
M05.CG.2.1.1

Classify twodimensional figures in a hierarchy based on properties.
