Geometric Sequences And Series

Published on 10/17/2008

Activity Overview

Students will represent and analyze mathematical situations and structures using algebraic symbols. They will also use mathematical models to represent and understand quantitative relationships.

Before the Activity

Provide each student with a copy of the attached .pdf document.

During the Activity

Students will:

  • Examine geometric sequences and series in Sequence mode.
  • Relate geometric sequences to their explicit forms.
  • Find the partial sums of a sequence in a table.
  • Determine if a geometric series in converging.
  • After the Activity

  • Review student answers
  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
