Measurement Standard for Grades 6-8

 

 

Expectations 

Instructional programs from prekindergarten through grade 12 should enable all students to—  In grades 6–8 all students should— 
Understand measurable attributes of objects and the units, systems, and processes of measurement
  • understand both metric and customary systems of measurement;
  • understand relationships among units and convert from one unit to another within the same system;
  • understand, select, and use units of appropriate size and type to measure angles, perimeter, area, surface area, and volume.
 
Apply appropriate techniques, tools, and formulas to determine measurements
  • use common benchmarks to select appropriate methods for estimating measurements;
  • select and apply techniques and tools to accurately find length, area, volume, and angle measures to appropriate levels of precision;
  • develop and use formulas to determine the circumference of circles and the area of triangles, parallelograms, trapezoids, and circles and develop strategies to find the area of more-complex shapes;
  • develop strategies to determine the surface area and volume of selected prisms, pyramids, and cylinders;
  • solve problems involving scale factors, using ratio and proportion;
  • solve simple problems involving rates and derived measurements for such attributes as velocity and density.
