Lesson I: SETS: AN INTRODUCTION Pre-requisite Concepts: Whole numbers
Objectives:
In this lesson, you are expected to:
1. Describe and illustrate
a. well-defined sets;
b. subsets;
c. universal set, and;
d. the null set.
2. Use Venn Diagrams to represent sets and subsets.
NOTE TO THE TEACHER:
This lesson looks easy and fast to teach but donโt be deceived. The introductory concepts are always crucial. What differentiates a set from any group is that a set is well defined. Emphasize this to the students. You may vary the activity by giving them a different set of objects to group. You may make this into a class activity by showing a poster of objects in front of the class or even make it into a game. The idea is for them to create their own well-defined groups according to what they see as common characteristics of elements in a group.
