Standard 2: Measurement

Resources

Benchmark

Indicator

 

A.   Select appropriate units to measure angles, circumference, surface area, mass and volume, using:

      • U.S. customary units; e.g., degrees, square feet, pounds, and other units as appropriate;

      • metric units; e.g., square meters, kilograms and other units as appropriate.

1.   Select appropriate units for measuring derived measurements; e.g., miles per hour, revolutions per minute.

 

B.   Convert units of length, area, volume, mass and time within the same measurement system.

1.   Convert units of area and volume within the same measurement system using proportional reasoning and a reference table when appropriate; e.g., square feet to square yards, cubic meters to cubic centimeters.

 

C.   Identify appropriate tools and apply appropriate techniques for measuring angles, perimeter or circumference and area of triangles, quadrilaterals, circles and composite shapes, and surface area and volume of prisms and cylinders.

1.   Use strategies to develop formulas for finding area of trapezoids and volume of cylinders and prisms.

2.   Develop strategies to find the area of composite shapes using the areas of triangles, parallelograms, circles and sectors.

 

D.   Select a tool and measure accurately to a specified level of             precision.

1.   Estimate a measurement to a greater degree of precision than the tool provides.

 

E.   Use problem solving techniques and technology as needed to solve problems involving length, weight, perimeter, area, volume, time and temperature.

1.   Solve problems involving proportional relationships and scale factors; e.g., scale models that require unit conversions within the same measurement system.

  

F.  Analyze and explain what happens to area and perimeter or surface area and volume when the dimensions of an object are changed.

1.     Describe what happens to the surface area and volume of a three-dimensional object when the measurements of the objects are changed; e.g. length of sides are doubled
