# Three Act Math Video- Bowl Full of Ice Cream

Concept- Volume

Three Act MathVideo Design by Jennifer Brokofsky and Ryan Banow

## Possible Curriculum Connections

Grade 5– SS5.3 Demonstrate an understanding of volume by:

• selecting and justifying referents for cm³ or m³ units
• estimating volume by using referents for cm³ or m³
• measuring and recording volume (cm³ or m³)
• constructing rectangular prisms for a given volume.

[C, CN, ME, PS, R, V]

Indicators

a) Provide referents for cm³ and m³ and explain the choice.
b) Describe strategies developed for selecting and using referents to determine approximate volume measurements in situations relevant to self, family, or community.
c) Estimate the volume of 3-D objects using personal referents.
d) Decide what standard cubic unit is represented by a specific referent, and verify.
e) Determine the volume of a 3-D object using manipulatives, describe the strategy used, and explain whether the volume is exact or an estimate.
f) Construct possible rectangular prisms for a given volume, identify the dimensions of each prism, and explain which prism would be most appropriate for a particular situation.

Grade 8- SS8.3 Demonstrate understanding of volume limited to right prisms and cylinders (concretely, pictorially, or symbolically) by:

• relating area to volume
• generalizing strategies and formulae
• analyzing the effect of orientation
• solving problems.

[CN, PS, R, V]

Indicators

a) Identify situations from one’s home, school, or community in which the volume of right prism or right cylinder would need to be determined.

b) Describe the relationship between the area of the base of a right prism or right cylinder and the volume of the 3-D object.

c) Generalize and apply formulas for determining the area of a right prism and right cylinder.

d) Explain the effect of changing the orientation of a right prism or right cylinder on the volume of the 3-D object.

e) Create and solve personally relevant problems involving the volume of right prisms and right cylinders.

## Act One- The Problem- Video

A child has to choose which bowl will hold the most ice cream a cylinder or a rectangular prism.

The key question that arises from this clip is:

• Which bowl will give the child more ice cream?

## Act Two- Classroom Connections

Key question that arises from this clip is:

• Which bowl will give the child more ice cream?

What might the students need to acquire as they work to solve this problem?

Dimensions of the Bowls:

## Act Three- The Solution- Video

The child fills each bowl with water and pours the water into two transparent glass measuring cups. This indicates that the rectangular prism holds more ice cream.
