Attributes of Polygons
Unit description: Students will extend their understanding of polygons as they classify them into categories such as triangles, quadrilaterals, pentagons, and hexagons. Students will break shapes into fractional parts.

Essential Outcomes of the Unit
Geometry- Reason with shapes and their attributes.
- NY-3.G.1 Recognize and classify polygons based on the number of sides and vertices (triangles, quadrilaterals, pentagons, and hexagons). Identify shapes that do not belong to one of the given subcategories. Note: Include both regular and irregular polygons, however, students need not use formal terms “regular” and “irregular,” e.g., students should be able to classify an irregular pentagon as “a pentagon,” but do not need to classify it as an “irregular pentagon.
- NY-3.G.2 Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole.
Essential Questions and Big Ideas
How do I identify polygons?
- Polygons are figures with straight lines that are connected.
- The type of polygon can be determined by counting the sides.
What are common types of polygons?
- A triangle is a shape with three sides and three angles
- A quadrilateral is a shape with four sides and four angles.
- A pentagon is a shape with five sides and five angles.
- A hexagon is a shape with six sides and six angles.
How can shapes be partitioned?
- A shape can be broken into parts of equal area which represent fractions.
