MGSE5.G.3
Understand that attributes belonging to a category of two-dimensional 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.
*PRIORTIZED:MGSE5.G.4
Classify two-dimensional figures in a hierarchy based on properties
(polygons, triangles and quadrilaterals).
Big
Ideas
•Two-Dimensional figures are
classified by their properties.
• Two-Dimensional figures can fit
into more than one category.
• Identify and describe properties
of two-dimensional figures more precisely
Concepts/Skills
to Maintain:
describe, analyze, create, and compare
properties of two-dimensional figures
• compare
and classify figures by their sides and angles
• examine the presence or absence of parallel
and perpendicular lines
• examine the presence or absence of angles of a
specified size to classify two-dimensional shapes • classify two-dimensional
shapes in a hierarchy based on properties
