Test Item Specifications
  • Item Type(s): This benchmark may be assessed using: MC , GR item(s)

  • Clarification :
    Students will analyze a situation to justify a strategy for calculating surface area and/or volume. 

    Students will apply formulas to solve problems related to surface area of right-rectangular prisms, nonoblique triangular prisms, right-square pyramids, and right circular cylinders. 

    Students will apply formulas to solve problems related to volume of right-rectangular prisms, right triangular prisms, right-square pyramids, right-circular cylinders, and cones. 

    Students will determine one or two dimension(s) of a threedimensional figure, given its volume or surface area and the other dimensions.

  • Content Limits :
    Dimensions of given figures will be whole numbers.

    Problems related to surface area will not include cones, but problems related to volume can include cones.

    In calculating surface area and volume of simple shapes, dimensions of given figures will be whole numbers.
  • Stimulus Attributes :
    Items should be set in a real-world or mathematical context.

    Graphics should be used in most of these items, as appropriate.

Lesson Plans

Wrapping Up Geometry (Lesson 2 of 2):

This lesson is 2 of 2 and is primarily formative in nature, but includes a summative assessment for students to take during the following class period. 

During the lesson, students will be reviewing for their assessment on the surface area formula for a right rectangular prism. 

 

Type: Lesson Plan

Wallpaper Woes Money Math: Lessons for Life:

Students hear a story about a middle-school student who wants to redecorate his bedroom. They measure the classroom wall dimensions, draw a scale model, and incorporate measurements for windows and doors to determine the area that could be covered by wallpaper. Students then hear more about the student's redecorating adventure and learn about expenses, budget constraints, and tradeoffs.

Teaching Ideas

Modeling: Making Matchsticks:

This lesson unit is intended to help you assess how well students are able to:

  • Interpret a situation and represent the variables mathematically.
  • Select appropriate mathematical methods.
  • Interpret and evaluate the data generated.
  • Communicate their reasoning clearly.
The context is estimating how many matchsticks (rectangular prisms) can be made from this tree (conic).

Packing For A L-o-o-o-ng Trip To Mars:

In this engineering task, students will apply concepts of volume to decide what they will need to take on a 2-1/2 year journey to Mars. Then plan how to fit everything into a 1-cubic-meter box, using only a measuring tape, pencil and paper, and math.
