## Area of Polygons

Standards:
6.G.1: Find area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.

• I can recognize and know how to compose and decompose polygons into triangles and rectangles.
• I can compare the area of a triangle to the area of the composed rectangle.
• I can apply the techniques of composing and/or decomposing to find the area of triangles, special quadrilaterals and polygons to solve mathematical and real world problems.
• I can discuss, develop and justify formulas for triangles and parallelograms (6th grade introduction).

6.G.3: Draw polygons in the coordinate plane given coordinates for the vertices; use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate. Apply these techniques in the context of solving real-world and mathematical problems.

• I can draw polygons in the coordinate plane.
• I can use coordinates (with the same x-coordinate or the same y-coordinate) to find the length of a side of a polygon.
• I can apply the technique of using coordinates to find the length of a side of a polygon drawn in the coordinate plane to solve real-world and mathematical problems.
