Downside Up

In this updated activity, students will explore patterns and formulate mathematical relationships through the Canstruction® exhibit ‘Downside Up.’ Begin with the starter slides for initial estimation attempts and discussions (You’ll find solutions to the starter in the speaker notes section in the slides), then identify the mathematical relationships in the arrangement of cans during the main activity.

📝Middle school students may find the activity a little challenging, particularly in deriving the formula, but with some guidance, we are sure they’ll tackle the challenge with enthusiasm!

⏰Around an hour, including the starter and main activity, with timing varying based on class discussion.
