This is an activity based on the picture book The Emperor’s Army
Students will be able to model their understanding of volume through creating models and calculating volume using a formula.
The volume of cuboids is found by multiplying the length by the height by the width. This is expressed in cubic units.

Summary:
This is another “mathematical adventure” in the Warlord series that takes place in ancient China. After being forced to flee the palace, the young apprentice discovers the terra-cotta army being built. He calculates the size of the army based on his measurements of the clay hole being dug.
Lesson Sequence:
Prior to reading, explore your students’ understanding of volume and seek out examples from their own lives when volume needs to be calculated or considered (filling drink bottles, packaging, pumping up sports balls etc). Compare and contrast the concept with those of perimeter and area. Create a chart to remind students about the measures
Feature | dimensions | expressed as |
perimeter | length (fence line: 1-D) | units: u |
area | length and width (carpet coverage: 2-D) | units squared: u2 |
volume | length and width and height (box: 3-D) | units cubed: u3 |
