It is a great tool to be used within the classroom. It can be used to monipulate numbers for grade postings, to teach a student to manage a budget, accounting, and much more. It can be used in everyday life which makes this program very useful and from my viewpoint nessary on the educational standpoint.
The book mentioned three major functions storing, calculationg, and presenting information. First, spreadsheet are programed to store information, usually numerical information. Second, and most important, spreadsheep support calculation functions, such as numerical contents of any combination within the cells. Third spreadsheet present the information using graphs and charts, as well as graphics.
If the cells of a spreadsheet are formated correctly than it can do much more that just calculate numbers. It can be used as a filling system to ceep records of grades of a teachers students rather than keeping a gradebook.
