Lesson Title Wrap it Up - Part 1
Unit Title Volume and Surface Area
NRS Level Level 4; Level 5; 
Length of Lesson 120 minutes
Lesson Purpose

The purpose of this lesson is to expand student knowledge of using the surface area formulas.  Students will use surface area formulas to calculate the surface area of rectangular and right prims, and pyramids as well as calculate missing dimensions.  The ability to determine the surface area and use and explain formulas is a major work of Level D Geometry.

Students will use many previously learned skills in this lesson in order to calculate surface area and the missing dimensions when given the surface area.  Students will need to have an understanding of substitution and solving equations for a variable.  Students will also need to be familiar with converting units of measure.

CCR Focus Standards
Geometry - Level C
Geometry - Level D
  • Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.

Supporting Standards
  • Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole- number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations). For example, use the formulas V = s^3 and A = 6 s^2 to find the volume and surface area of a cube with sides of length s = 1/2.

  • Solve real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers.

  • Apply concepts of density based on area and volume in modeling situations (e.g., persons per square mile, BTUs per cubic foot).* [Also see 7.RP.3]

Standards for Mathematical Practice
  • Make sense of problems and persevere in solving them. (MP.1)

  • Reason abstractly and quantitatively. (MP.2)

  • Attend to precision. (MP.6)

KYAE Employability Standards
  • E.1 Effectively contribute to a team through cooperation, leadership, and giving and accepting critical feedback to work toward a common goal.

  • E.5 Utilize resources responsibly.
