Lesson 4: (Optional) Using Technology to Work with Sequences
• Use a spreadsheet to continue a sequence by applying a recursive rule.
• Use graphing technology to plot points corresponding to terms of a sequence.
Lesson Narrative
This lesson is optional. The purpose 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 " ll down" functionality. With graphing technology, they learn to plot a list of points entered in a table, where a rule can be used 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).
Note: The cool-down was accidentally printed in the workbooks for the pilot. If you are using the student workbooks, please adjust your plans accordingly.
Required Materials Graphing technology
Spreadsheet technology Required Preparation
Acquire devices that can run GeoGebra (recommended) or other spreadsheet technology and Desmos (recommended) or other graphing technology. It is ideal if each student has their own device. (A GeoGebra Spreadsheet and Desmos Graphing Calculator are available under Math Tools.)
Student Learning Goals
Let’s use technology to create a sequence.
4.1 Where Does It Live?
Warm Up: 5 minutes
The purpose of this activity is to gain familiarity with the names of cells in a spreadsheet and to prepare students for continuing sequences using technology.
Launch
Provide access to spreadsheet technology for each student. If students are using the digital version of the materials, show them how to open the GeoGebra Spreadsheet in the math tools.
