G.2D.1.6 Apply the properties of polygons to solve real-world and mathematical problems involving perimeter and area (e.g., triangles, special quadrilaterals, regular polygons – up to 12 sided figures, composite figures).

In a Nutshell

Students will apply the properties of polygons to solve real-world and mathematical problems involving perimeter and area.

Student Actions	Teacher Actions
Develop a Deep and Flexible Conceptual Understanding: Students will be able to articulate the difference between area and perimeter and explain the units for area are squared. Develop Accurate and Appropriate Procedural Fluency: Students will use diagrams and descriptions of polygons to find the area and perimeter. Develop Strategies for Problem Solving: Students will solve a variety of tasks that require the use of perimeter, area, or both.	Teachers will pose purposeful questions in order to lead classroom discussions over solving a variety of tasks that require students to explain their chosen method of solution and defend the “reasonableness” of their final answer. Teachers will implement tasks to the whole class that require students to interpret diagrams for the needed information to solve for perimeter and area in order to promote reasoning and problem solving skills. Teachers will use and connect representations between the mathematical and real-world situations that allow students to solve for perimeter and/or area in a real-world context.
Key Understandings	Misconceptions
Students understand how to find the perimeter of different types of polygons in mathematical and real world situations Students understand how to determine the area of different types of polygons in mathematical and real world situations.	Students confuse area with perimeter. Students do not use the correct units of measurement when labeling the perimeter or area of a polygon.
