Circulate the homework sheet.  This emphasizes a wide variety of problems:

1)     Finding if a series has a sum

2)     Finding the sum of the first several terms

3)     Finding the sum of an infinite number of terms

4)     Real World Application (bouncy ball problem)

- Requires the students to Reason Abstractly (MP 2)

5)     Making use of structure to analyze infinite arithmetic series (MP 7)
