In the computer center, 
management and routines must be practiced before you could shift the focus to learning content. Once you have your management strategies in place, the rest will be smooth sailing.
Here are some routines for you to teach 
first week of school:
 1. Use a word to get their attention and make them 
quit their hands from the keyboard/mouse. Some teachers preffer to make them put their hands in their heads. Now you have their complete attention to teach your topic. 
Also you can use a poster to remaind it.
 2. Find a helper. There are kids who have more practice with the computer, they can help you with other students in a computer issue. 
This makes management easier for you. This kid can also be aware for others to fill the "Computer Use Worksheet" and make sure they are following the rules. The Computer Police:
 3. When teaching a many steps lesson, students tend to forget the first steps. I use 
direction sheets like I read in 
this post.
  
4. Is better to name things in the right way. I use posters and tags to label every part of the computer, so they can remember and learn it all. After a while I remove labels and 
students should know every computer part´s name. These labeled tags and posters are available in my 
Computer Center complete pack.
 5. There are other computer routines that must be taught, like the correct order to turn on and off the computer, how to save quit an USB stick, and the
 rules for using the computer and internet:
