IM 1.11 Adding Up

The goal of this lesson is for students to encounter several situations where it makes sense to find the sum of a sequence, defined here as adding up the value of the terms of the sequence. At this point, the number of terms students need to sum is kept short since the summing is by hand. In a future unit students use polynomial identities to develop a formula to sum the first  terms of any geometric sequence. The main activities in this lesson are meant to be relatively unscaffolded, giving students the opportunity to make sense of the problems using the tools they have worked with throughout this unit, such as tables, graphs, and equations (MP1).
