This lesson is optional. The purpose of the lesson is to take time to explicitly teach students how to use spreadsheets and graphing technology in ways that are useful for working with sequences. In a spreadsheet, they learn to refer to a cell's address, enter a formula that uses the contents of a cell, and use the “fill down” functionality. With graphing technology, they learn to plot a list of points entered in a table and use a rule to determine the -coordinate based on the corresponding value of the -coordinate. By taking part in this lesson and having access to these tools throughout the unit, students will be in a position to choose appropriate tools strategically (MP5).

Use available technology to test all directions in activities prior to the start of the lesson.
