As a culminating assessment for a PreAlgebra unit in decimals, percents and graphing, I decided to teach students about the useful tool of a Google Spreadsheet. After introducing some basic terminology and functionality of a spreadsheet, students will be given $400 to spend at Bed, Bath and Beyond to redecorate their room. It is my hope that they will find this activity engaging and, at the same time, teach them how easy calculations can be when using a spreadsheet. I will also introduce the basics of creating a bar chart. I thought I’d share in case anyone else was looking for this type of activity.
