                Time Charts







               Practice Activity






                             Technology Overview            Being able to show your time spent on a project
                             in the form of a chart is an important skill. There are specialized software programs
                             that you can use to record time spent on a task, but a spreadsheet program can take
                             care of nearly everything you need to record and do any calculations for you.
                             Presenting the data on the worksheet can be a clear and easy way to see your data.
                             In this activity, you will use a spreadsheet program to make calculations.
                             Content Overview           Working at Reading Treasures Bookstore is a great
                             deal of fun. Besides getting to see all the new titles as soon as they come out, you
                             also shelve books, run the register, help customers find or order books, clean, and
                             perform administrative tasks such as taking care of the paperwork for orders. In this
                             activity, you will fill out a timecard to show how you spent your time for a five-day
                             week.
