Session 6 - Spreadsheet Assignment Introduction to creating a classroom spreadsheet. Note: We are NOT going to do a grade book!

What is a spreadsheet? A simple way to think of a spreadsheet is as a blank sheet of paper with columns and rows. Each intersection of a column and row results in a cell where data can be recorded. A spreadsheet application is a software program in which you can enter words and numbers as well as formulas to calculate numbers. A spreadsheet might be used by accountants to keep a ledger or by a teacher to create an electronic grade book. Unlike the paper version the computer version can automatically manipulate, calculate and display data.
