Part I: Preliminary Setup


The purpose of this lab is to help you become accustomed to using the Geometer's Sketchpad (GSP). This program will be used throughout the entire school year. Therefore, it is important that you learn the basics before we get into the difficult material. Answer the questions in the space provided. Something should happen each time a question is asked and you are to describe what happens. If nothing happens, try again.

Computer Disk:

First things first. We are now going to format your disk for use on a Macintosh computer. Insert your disk into the drive. You will see a screen similiar to the one below.

Enter the name you want for your disk (your name usually works best).

Click on "Initialize." The computer will then tell you that it will erase all information on the disk.

Click on "Continue."

If nothing happens when you put your disk in, you will need to erase all the information on the disk by doing the following:

  1. Make sure the disk is highlighted.
  2. Choose "Erase Disk" under the SPECIAL menu.
  3. Enter the name you want for your disk (your name usually works best).

If the computer will not let you "Erase Disk," then just put your name on the disk by clicking once on the disk title. Regardless of which method you use, it will take the computer a few minutes to do its thing. Be patient. Once the computer has finished working, your disk is ready to be used. This process should only be done once. If you do it again later in the year it will erase all information stored on the disk.
