Using marshmallows to introduce the concept of volume is the perfect way to get students to buy in while learning the basics of this fifth grade standard.

This three part lesson set has been designed to introduce the concepts of length, width, height, and volume in a hands-on way using marshmallows at the "cubes". The students will build rectangular prisms using marshmallows, diagraming their creations along the way.

The first lesson is a directed task set in which the students will be guided through six different tasks involving various volumes and dimensions. This is set up in a gradual release model where, as the tasks go on, more and more responsibility is left to the students instead of the teacher.

The second lesson is a constructed response where the students take what they learned about volume and apply it independently through an application task.

The third lesson is where the teacher checks for understanding through a mini-anchor chart and exit ticket.

Everything you will need (minus the baggies of mini-marshmallows) is included in this print and go file! The only thing you need to prep are the marshmallows for your students.

to see state-specific standards (only available in the US).
Find the volume of a right rectangular prism with whole-number side lengths by packing it with unit cubes, and show that the volume is the same as would be found by multiplying the edge lengths, equivalently by multiplying the height by the area of the base. Represent threefold whole-number products as volumes, e.g., to represent the associative property of multiplication.
Relate volume to the operations of multiplication and addition and solve real world and mathematical problems involving volume.
Measure volumes by counting unit cubes, using cubic cm, cubic in, cubic ft, and improvised units.
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.
