Week 4

I have used Spreadsheets before and I think they are very useful. I am secretary of my sorority so I have to have all the information organized. Spreadsheets provide a lot of useful tools for high school math teachers so I would definitely use it in my classroom. It is a great way to keep records of grades, attendance, and even a great way for creating homework assignments.
As a teacher, it is more beneficial to use spreasheet rather than a calculator. With the spreadsheet you can visually see what the computer is doing with the grades. The computer, itself, calculates the average. Because the computer calculates the averages there is less room for calculation errors that could be proudced by single handedly punching in numbers in the calculator.
The three primary functions that the book mentions are: storing, calculating, and presenting information. Excel does indeed provide these functions. Ofcourse it stores information that we have inputed. What is great about it is that it will do the calculations for you once you find an expression for it. Presenting information is a great way to make homework assignments for the using graphs, charts, and such tools.
