Objective: 

The student(s) will recognize the symbol for set and will demonstrate 
the rules of set. 

Materials Needed: 

A random sample of materials, some of which have a common factor 
(color, shape, type of material, weight - mass, or other physical 
property). 

Procedure:

The teacher (or students) will provide individual items.  The 
student is asked to list the characteristics, or properties of the 
object.  He (or she) is then asked to compare his list with a fellow 
student's list to make a master list.  This step may be repeated more 
than once depending on the size of the class, and the comprehension of 
the student(s) regarding the categorizing, or classification process.  
The teacher may ask for a volunteer to put his list on the board for 
purposes of comparison, and illustration.  The teacher will then 
introduce the term and notation for set, and will establish the rules 
for inclusion or exclusion from a particular set.  Following a 
demonstration, new materials (or objects) will be introduced and used 
by the student to test his (or her) understanding.  Abstract symbols 
are now introduced with further demonstration and testing by teacher 
and student.
