Module 5 Lesson 3Compose and decompose right rectangular prisms using
layers.
Based upon lessons created by Common Core,Inc
Stephen J. O’Connor
• 5.MD.3 Recognize volume as an attribute of solid figures and understand concepts of volume measurement.
• a. A cube with side length 1 unit, called a “unit cube,” is said to have “one cubic unit” of volume, and can be used to measure volume.
• b. A solid figure which can be packed without gaps or overlaps using n unit cubes is said to have a volume of n cubic units.
• 5.MD.4 Measure volumes by counting unit cubes, using cubic cm, cubic in, cubic ft, and improvised units.
Common CoreStandards
• I can compose and decompose right rectangular prisms using layers.

ApplicationProblem
An ice cube tray has two rows of 8 cubes in each. How many ice cubes are in a stack of 12 ice cube trays?
Draw a picture to explain your reasoning.
Problem 1
Concept Developmen
t Build this with your own cubes.

Concept Developmen
t What is the volume?

Concept Developmen
t Let’s add layers horizontally. Add another layer next to the first one.

tLet’s record how we built the layers. Use the first rectangle in the row of
your recording sheet.

Now, imagine that we could partition this prism into layers like a cake, like our ice cube trays.
What might that look like? Work with your partner to show the layers on the next prism in the row and tell how many cubes would be in
each. Use your cubes to help you.

tWork with your partner to find one last way that we can partition this prism into layers. Label the
layers with the number of cubes on the third prism in the row, and write a number sentence
to explain your thinking.

Use the set of cubes on your recording sheet to show the three ways of layering using the same
system we just did with our 2 by 2 by 5 rectangular prism.

Problem 1
Concept Developmen
t Imagine what the bottom layer of this prism would look like. Describe it to your partner and
then build it.
Problem 1
Concept Developmen
t
Here’s the same prism, but without the unit cubes drawn. How might we represent the
bottom layer on this picture? Use your recording sheet, and talk to your partner.
Problem 1
Concept Developmen
t What other ways could we partition this prism into layers? Turn and talk, then draw a picture of
your thinking on the recording sheet.
