Double Tree

Published on 08/28/2010

Activity Overview

Students visually model the sequence 2n for n = 1...8 by drawing line segments that represent a tree that doubles its height every year. They then extend the sequence "backward though time" over negative values for n.

Key Steps

  • Image

    In this problem, students model the growth of a tree that doubles each year using the sequence 2n. They graph the sequence by creating segments and then measuring them.

  • Image

    After building the sequence on the graph, students will write it with sequence notation and create it numerically on a Lists & Spreadsheet page.
