Measurement Standard for Grades 3-5

 

 

Expectations 

Instructional programs from prekindergarten through grade 12 should enable all students to—  In grades 3–5 all students should— 
Understand measurable attributes of objects and the units, systems, and processes of measurement
  • understand such attributes as length, area, weight, volume, and size of angle and select the appropriate type of unit for measuring each attribute;
  • understand the need for measuring with standard units and become familiar with standard units in the customary and metric systems;
  • carry out simple unit conversions, such as from centimeters to meters, within a system of measurement;
  • understand that measurements are approximations and how differences in units affect precision;
  • explore what happens to measurements of a two-dimensional shape such as its perimeter and area when the shape is changed in some way.
 
Apply appropriate techniques, tools, and formulas to determine measurements
  • develop strategies for estimating the perimeters, areas, and volumes of irregular shapes;
  • select and apply appropriate standard units and tools to measure length, area, volume, weight, time, temperature, and the size of angles;
  • select and use benchmarks to estimate measurements;
  • develop, understand, and use formulas to find the area of rectangles and related triangles and parallelograms;
  • develop strategies to determine the surface areas and volumes of rectangular solids.
