Go over homework (page 19-37 odds).

Content Objectives (1 min.)
Students will find the sum of geometric series.

Language Objectives (1 min.)
Students will read the text and take notes on geometric series.


Activities (35 min.)

Just as we found the sum of arithmetic series, we can also find the sum of geometric series. This is covered in section 11-4, pages 670-673. Read and take notes on the formula for the sum and the examples.

Let's try 5-15 as a class from page 673.
