Spreadsheets are a good way to be organized. Personally, I like them because they are a good way to display calculations, data, and graphs/charts. This actually is really good if used in the classroom for the students and the teacher. The teacher can use it for the gradebook and utilize it in the classroom for the students homework or in class assignment.
Most importantly, teachers use spreadsheets to record their grades from their students. They also can use it by creating charts for instruction or analyze types of data for in the classroom. Spreadsheets are really good for number crunching and allows mathematical formulas to be applied. It is a large, complex calculator that can calculate complex mathematics that need to be carried out on large amounts of numerical data. Spreadsheets are good for storing, calculating, and presenting information.
