MA.5.GR.3 is a B.E.S.T. standard. These are the benchmarks under it.

Teacher's field guide

What Students Need to Do: Students use the length, width, and height of a rectangular prism to find how much space it holds. They connect layers of unit cubes to multiplication and report answers in cubic units.
What Mastery Looks Like: Students choose and use V = l × w × h or V = B × h correctly. They show their work and label the answer in cubic units. They can explain how layers of unit cubes match the calculation.
Common Misconceptions: Students may add the three dimensions instead of multiplying them. They may label answers with square units rather than cubic units. Some count only visible cubes in a drawing and miss hidden layers.
How to Assess It: Exit ticket: A storage box is 8 inches long, 5 inches wide, and 3 inches high. Find its volume and explain the unit used.

Lesson moves

Build rectangular prisms with linking cubes, record each dimension, then compare counted cubes with the product of length, width, and height.
Ask students to explain why multiplying the base area by the height gives the total number of unit cubes.
Play Volume Match by pairing prism diagrams, dimension cards, equations, and volume cards within a timed round.
Measure a cereal box to the nearest whole inch, calculate its volume, and compare it with two other classroom packages.
