CCSS.Math.Content.5.MD.C.3
The standard
Recognize volume as an attribute of solid figures and understand concepts of volume measurement.
Common Core State Standards for Mathematics · Measurement and Data
What this standard means
Students need to see volume as the amount of space inside a solid shape, not just another formula. They should connect volume to filling a box with unit cubes, with no gaps or overlaps. They also need to understand that each cube is one cubic unit.
Mastery looks like students building or picturing a rectangular prism and explaining how the cubes fill it. They can tell the difference between area and volume. Common sticking points are counting only visible cubes, using square units instead of cubic units, and thinking taller always means more volume without checking all dimensions.
Ways to teach it
- Give pairs centimeter cubes and small open boxes, then have them fill each box and count the total cubes used.
- Ask students to write: How is filling a box with cubes different from covering the bottom with squares?
- Show a drawn prism made of unit cubes and ask students to name the volume and the unit in one minute.
- Bring in two food boxes and ask which holds more, then have students explain what information they need to know.
