What 5.MD.4 Means in Plain English

Fifth graders find volume by counting. They fill a shoebox with inch cubes, or count the centimeter cubes in a drawn stack, or pack a bin with identical blocks and report the volume in those blocks. The unit is named every time: 36 cubic inches, or 15 blocks.

Counting is slow on purpose. Once students see that every layer of a box holds the same number of cubes, they are ready for the formula (5.MD.5). An L-shaped stack is counted in parts, the additive idea 5.MD.5c makes official. Fractional edges arrive in 6th grade (6.G.2).

5.MD.4 I Can Statements

  • I can count unit cubes to find the volume of a solid.
  • I can report volume in cubic centimeters, cubic inches or cubic feet.
  • I can measure volume with an improvised unit, like sugar cubes.

5.MD.4 Worked Example

An L-shaped stack of centimeter cubes: the kind of solid where counting carefully beats guessing.

Problem

A solid is built from centimeter cubes. The bottom layer is 5 cubes long and 2 cubes wide. On top of one end sits a second layer 2 cubes long and 2 cubes wide. What is the volume?

Counting cubes in an L-shaped stack
  1. Name the unit before counting: each cube is 1 cm on every edge, so each one is 1 cubic centimeter.1 cube = 1 cm³
  2. Count the bottom layer. It is a rectangle 5 cubes long and 2 wide, so count by rows of 5.Bottom layer: 5 + 5 = 10 cubes
  3. Count the top layer. It covers only one end: 2 cubes long and 2 wide.Top layer: 2 + 2 = 4 cubes
  4. Every cube is counted once and none is hidden, so add the layers.10 + 4 = 14 cubes
Answer14 cubic centimeters

Check it: Count by columns instead: 6 columns are 1 cube tall (6 cubes) and 4 columns are 2 cubes tall (8 cubes). 6 + 8 = 14, the same total.

Common Mistakes with 5.MD.4

Counting faces instead of cubes

Counting every visible square on the drawing and calling that the volume

Try this: Hand out real cubes and rebuild the drawing. One cube shows up to three faces, so counting squares overcounts badly.

Forgetting the cubes underneath

“The top layer has 4 cubes, plus the ones I can see in front”

Try this: Count layer by layer from the bottom, saying each total out loud: 10 in the bottom layer, then 4 more on top.

Dropping the unit

“The volume is 14”

Try this: Require the unit in every answer. 14 cubic centimeters and 14 cubic inches are very different boxes, and 14 alone is a count.

Quick Check

  1. A box is packed with 3 layers of 12 inch cubes. What is its volume?
  2. A stack has a bottom layer of 8 centimeter cubes and a top layer of 3. What is its volume?
  3. A bin is filled with 20 identical blocks with no gaps. What is its volume, and in what unit?
