Opening Activities

Can you imagine a tower built out of one million pennies? How tall would it be? In this lesson, you will work with your team to predict just how tall such a tower would be. To make sense of this question, you will measure some pennies and investigate the relationship between the height of a tower of pennies and the number of pennies in that tower. This is an example of a special relationship called a proportional relationship, which you will learn more about later in this course.

How tall would a tower of a million pennies be?

Would it be taller than your school building?

Would it be taller than Mount Everest?

Discuss these questions with your team and make a prediction.

1-25. TINY TOWERS

To begin to investigate this question, start by collecting data. Parts (a) and (b) will lead you through the data-collection process.

How many pennies does it take to build a tower that is one centimeter tall? Use the tools provided by your teacher to answer this question.

On your own paper, create a table like the one at right. Work with your team to complete the missing information. Be prepared to explain your reasoning to the class.
