** The only way to learn mathematics is by doing it! ** Complete each
assignment to the best of your ability, and get help when you are confused.
Come to class prepared with questions. Don't hesitate to seek help from
other students. Sometimes the point of view of someone who has just figured
something out can be the most helpful.

* Content:* The concept of a ** function ** is basic to all
of mathematics. Although elementary students don't encounter the formal
notion of a function, examples of functions are everywhere. We will
study proportional reasoning, percents, data and chance, and do some
modeling using Excel spreadsheets.

* Computers:* Later on in the course we will spend some time
working with computers, specifically the spreadsheet * Microsoft
Excel*. The CSU system has signed a licensing agreement with
Microsoft which makes Excel and many other MS programs available to CSUH
students, faculty, and staff at nominal cost. Those of you with access
to computers at home or work can install Excel there if you don't have
it already. It's also available in all the PC computer labs around
campus. If you are not yet comfortable with using computers or
spreadsheets, you may want to get a head start. There are CBT Systems
On-Line Computer-Based Training Courses available. Contact the help desk
885-4357 or send an e-mail message to *
helpdesk@csuhayward.edu* .

Homework is due on Thursdays at the beginning of class. Try to start it early so you have the opportunity to ask questions the Tuesday before. I will try to keep a couple of weeks ahead, so those of you who would like to work ahead can.
