Unit of Instruction  7: TwoDimensional Measurements 
Standard(s) Taught 

MAFS.912.G.C2.5 Derive using similarity the fact that the length of the arc intercepted by an angle is proportional to the radius, derive the formula for the area of a sector. MAFS.912.GGMD.1.1 Give an informal argument for the formulas for the circumference of a circle, area of a circle, volume of a cylinder, pyramid, and cone. (Use dissection arguments, Cavalieri’s principle, and informal limit arguments.) MAFS.912.GGPE.2.7 Use coordinates to compute perimeters of polygons and areas of triangles and rectangles, e.g., using the distance formula. MAFS.912.GMG.1.1 Use geometric shapes, their measures, and their properties to describe objects. MAFS.912.GMG.1.2 Apply concepts of density based on area and volume in modeling situations (e.g., persons per square mile). MAFS.912.GMG.1.3 Apply geometric methods to solve design problems (e.g., designing an object or structure to satisfy physical constraints or minimize cost; working with typographic grid systems based on ratios).
