Identifying File Types, Purposes, and Extensions Test KEY
Materials Needed:
Copies of Notes Organizer, instruction sheets, and test
Equipment Needed:
 Computer and projector for presentation
 Computers for individual student use
Learner
As a class, have the students organize themselves into like groupings (examples: male and
female; grade levels; age). Then, have the students organize themselves into subgroups
(example: main group is age, subgroups male and female).
Note: the objective of this exercise is to help the students understand the need for organization
and that there are several ways to organize the same information.
Introduction
MI
Introduction (LSI Quadrant I):
ASK, “Have you ever gone to your computer to complete something you were
working on and not been able to find where you saved it?”
ASK, “You can’t remember what you named it and you end up starting all over
again?”
SAY, “That’s why it’s important to establish a good folder and organizational system
for your files.”
SAY, “Have you ever opened a file and it was just a bunch of symbols? That’s
because you used the wrong software to open the file.”
