2021 Oregon Math Guidance: 3.GM.B.4

 ODE and Oregon Math Project Logo

Cluster: 3.GM.B - Solve problems involving measurement and estimation.


 Standards Statement (2021):

Measure, estimate and solve problems in authentic contexts that involve liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l).

 Standards Guidance:


  • Students should have an opportunity to compare capacity by filling one container with something and then pouring this amount into the comparison container.
  • Students may use drawings (such as a beaker with a measurement scale) to represent the problem. This standard does not include conversions between units.
  • The standard includes making reasonable estimates, use benchmarks to measure weight, and capacity.


  • The terminology below is used to clarify expectations for the teaching professional.  Students are not required to use this terminology when engaging with the learning objective.
    • Customary measurement units include weight (oz., lbs., tons) capacity (fl. oz, cups, pints, quarts, gallons), length (in., ft., yds., miles).


  • Excludes compound units such as cm^3 and finding the geometric volume of a container.
  • Excludes multiplicative comparison problems (problems involving notions of “times as much”).
  • Students are not required to memorize the conversion factors.
  • Students extend understanding of measuring length in different measurement systems (e.g. grams (g) to ounces (oz), kilograms to pounds (lb), liters (l) to quarts (qt)/gallons (gal), etc).


  • Identify and use the appropriate tools and units of measurement, both customary and metric, to solve one-step word problems using the four operations involving weight, mass, liquid volume, and capacity (within the same system and unit).

Teaching Strategies

  • Add, subtract, multiply or divide to solve one-step word problems involving masses or volumes that are given in the same units.
  • Students should have opportunities to physically measure objects.
  • Record measurement equivalents in a two-column table and/or double number line.
