When you have a lot of data, it can sometimes be difficult to analyze all of the information in your worksheet. PivotTables can help make your worksheets more manageable by summarizing data and allowing you to manipulate it in different ways.
In this video (Part 1 of 2), GCF Learn Free will show you how to insert and edit a PivotTable.

Tech-Time is a category on the Tech Teachers web site that consists of short videos of interest that a teacher can use to show to his/her class at the end of the day/cycle/lesson to generate discussion, inspire, create interest, inform or perhaps even help solidify some of the concepts being taught in CAT "theory".
I try find videos that I can use in my class and share them here on the web site in the category called Tech-Time. I hope you can use these videos too for your classes.
A folder with ALL featured Tech-Time videos in MP4 format is available in the Resources section
