Mrs. Camp's Fourth Grade did this lesson in their school's computer lab. It was a fun way to become familiar with spreadsheets and how they relate to student's lives. Before you go into the lab to start your Excel project, you will need your data that you will be entering. You will need to keep a time diary for a week. Enter activities you did such as sleeping, eating, video games, ETC. Write down the amount of time you spent on these activities.
