A. Preparation:
• Prepare the necessary
materials, including the
textbook and any
supplementary resources.
• Arrange the classroom in a
way that facilitates group
discussions and activities.
B. Motivation:
• Ask students about their
experiences with groups or
collections of objects.
• Discuss the concept of a
set and how it relates to
these everyday
experiences.
C. Lesson Proper:
1. Introduce the definition of a
set and its basic elements
(elements, members,
universal set, empty set).
2. Discuss the different types
of sets: finite and infinite
sets, equal sets, equivalent
sets, subsets, and proper
subsets.
3. Provide examples and non-
examples to illustrate each
type of set.
4. Teach the notation used to
represent sets, including
the roster method and the
set-builder notation.
D. Activity:
• Divide the students into
small groups.
• Provide each group with a
set of objects and ask them
A. Preparation:
• Review the concepts covered in Lesson
1.1.
• Prepare the materials, including the
textbook, whiteboard, and markers or
chalk.
B. Motivation:
• Ask students to recall the types of sets
discussed in the previous lesson.
• Discuss real-life scenarios where basic
set operations can be applied.
C. Lesson Proper:
1. Review the concepts of union,
intersection, and complement of sets.
2. Demonstrate how to perform basic set
operations using the roster method and
Venn diagrams.
3. Provide examples and non-examples to
illustrate each operation.
4. Discuss the properties of set operations,
such as commutativity, associativity, and
distributivity.
D. Activity:
• Divide the students into pairs or small
groups.
• Provide each group with a set of objects
and ask them to perform the basic set
operations discussed.
• Have the groups present their findings to
the class using Venn diagrams.
E. Generalization:
• Summarize the main points discussed
during the lesson.
• Highlight the importance of
understanding and applying basic set
operations in problem-solving.

to describe the set using
the concepts and notation
learned.
• Have the groups present
their findings to the class.
E. Generalization:
• Summarize the main points
discussed during the
lesson.
