Benchmarks in This Standard
MA.6.GR.2 is a B.E.S.T. standard. These are the benchmarks under it.
- MA.6.GR.2.1
Derive a formula for the area of a right triangle using a rectangle. Apply a formula to find the area of a triangle.
- MA.6.GR.2.2
Solve mathematical and real-world problems involving the area of quadrilaterals and composite figures by decomposing them into triangles or rectangles.
- MA.6.GR.2.3
Solve mathematical and real-world problems involving the volume of right rectangular prisms with positive rational number edge lengths using a visual model and ...
- MA.6.GR.2.4
Given a mathematical or real-world context, find the surface area of right rectangular prisms and right rectangular pyramids using the figure’s net.

What This Cluster Means
What Students Need to Do
- Students draw or build models of flat figures and solids. They use dimensions and formulas to solve for area, surface area, or volume in context.
What Mastery Looks Like
- Students break composite figures into familiar shapes and use nets or diagrams for solids. They choose the correct formula, show calculations, and label square or cubic units.
Common Misconceptions
- Students may confuse perimeter, area, surface area, and volume. They may leave out faces, use the wrong dimensions, or label answers with incorrect units.
How to Assess It
- Give an exit ticket: A 10-by-8 rectangle has a 4-by-3 corner removed. Find the remaining area, then explain your steps.

Ways to Teach It
Build rectangular prisms with centimeter cubes, record each volume, then draw and measure a net for each prism.
Compare prisms measuring 2 by 3 by 12 and 3 by 4 by 6, then explain why equal volumes can have different surface areas.
Play a card match using figure diagrams, dimensions, formulas, and calculated areas or volumes.
Design a cereal box with a set volume, then calculate how much cardboard its net requires.
