#### Introduction

(3 minutes)
• Show a box of any size and ask students to think about all the books that may fit into the box. Allow them to share their ideas aloud with the class and choose books.
• Integrate some of the vocabulary words relating to volume (e.g., "length," "width," "height") as you model restating their answers.
• Have a volunteer check the guesses by trying to put the books into the box. Emphasize that they added volume to the box with each book they added to show that volume is additive.
• Explain that today they'll learn about why they should know the volume of boxes and how it will help them with packaging.
