Actions

MOD.1 Modeling

  • Mathematical modeling and statistical problem-solving are extensive, cyclical processes that can be used to answer significant real-world problems.

    • 1 Use the full Mathematical Modeling Cycle or Statistical Problem-Solving Cycle to answer a real-world problem of particular student interest, incorporating standards from across the course.

MOD.2 Financial Planning and Management

  • Mathematical models involving growth and decay are useful in solving real-world problems involving borrowing and investing; spreadsheets are a frequently-used and powerful tool to assist with modeling financial situations.

    • 2 Use elements of the Mathematical Modeling Cycle to solve real-world problems involving finances.

    • 3 Organize and display financial information using arithmetic sequences to represent simple interest and straight-line depreciation.

    • 4 Organize and display financial information using geometric sequences to represent compound interest and proportional depreciation, including periodic (yearly, monthly, weekly) and continuous compounding.

      • 4.a Explain the relationship between annual percentage yield (APY) and annual percentage rate (APR) as values for r in the formulas A=P(1+r)t and A=Pert.

    • 5 Compare simple and compound interest, and straight-line and proportional depreciation.

    • 6 Investigate growth and reduction of credit card debt using spreadsheets, including variables such as beginning balance, payment structures, credits, interest rates, new purchases, finance charges, and fees.

    • 7 Compare and contrast housing finance options including renting, leasing to purchase, purchasing with a mortgage, and purchasing with cash.

      • 7.a Research and evaluate various mortgage products available to consumers.

      • 7.b Compare monthly mortgage payments for different terms, interest rates, and down payments.

      • 7.c Analyze the financial consequence of buying a home (mortgage payments vs. potentially increasing resale value) versus investing the money saved when renting, assuming that renting is the less expensive option.

    • 8 Investigate the advantages and disadvantages of various means of paying for an automobile, including leasing, purchasing by cash, and purchasing by loan.

MOD.3 Design in Three Dimensions

  • Two- and three-dimensional representations, coordinates systems, geometric transformations, and scale models are useful tools in planning, designing, and constructing solutions to real-world problems.

    • 9 Use the Mathematical Modeling Cycle to solve real-world problems involving the design of three-dimensional objects.

    • 10 Construct a two-dimensional visual representation of a three-dimensional object or structure.

      • 10.a Determine the level of precision and the appropriate tools for taking the measurements in constructing a two-dimensional visual representation of a three-dimensional object or structure.

      • 10.b Create an elevation drawing to represent a given solid structure, using technology where appropriate.

      • 10.c Determine which measurements cannot be taken directly and must be calculated based on other measurements when constructing a two-dimensional visual representation of a three-dimensional object or structure.

      • 10.d Determine an appropriate means to visually represent an object or structure, such as drawings on paper or graphics on computer screens.

    • 11 Plot coordinates on a three-dimensional Cartesian coordinate system and use relationships between coordinates to solve design problems.

      • 11.a Describe the features of a three-dimensional Cartesian coordinate system and use them to graph points.

      • 11.b Graph a point in space as the vertex of a right prism drawn in the appropriate octant with edges along the x, y, and z axes.

      • 11.c Find the distance between two objects in space given the coordinates of each.

      • 11.d Find the midpoint between two objects in space given the coordinates of each.

    • 12 Use technology and other tools to explore the results of simple transformations using three- dimensional coordinates, including translations in the x, y, and/or z directions; rotations of 90°, 180°, or 270° about the x, y, and z axes; reflections over the xy, yz, and xz planes; and dilations from the origin.

    • 13 Create a scale model of a complex three-dimensional structure based on observed measurements and indirect measurements, using translations, reflections, rotations, and dilations of its components.
