Focus: Problem Solving with Area, Perimeter, Volume, and Surface Area

The student will make ballpark comparisons between measurements in the U.S. Customary System of measurement and measurements in the metric system. 
Essential Knowledge and Skills
  • Estimate the conversion of units of length, weight/mass, volume, and temperature between the U.S. Customary system and the metric system by using ballpark comparisons.
  • Estimate measurements by comparing the object to be measured against a benchmark.
Essential Understandings
  • What is the difference between weight and mass? Weight and mass are different. Mass is the amount of matter in an object. Weight is the pull of gravity on the mass of an object. The mass of an object remains the same regardless of its location. The weight of an object changes dependent on the gravitational pull at its location.
  • How do you determine which units to use at different times? Units of measure are determined by the attributes of the object being measured. Measures of length are expressed in linear units, measures of area are expressed in square units, and measures of volume are expressed in cubic units.
  • Why are there two different measurement systems? Measurement systems are conventions invented by different cultures to meet their needs. The U.S. Customary System is the preferred method in the United States. The metric system is the preferred system worldwide.
