INTRODUCTION: 1. Begin the lesson by asking students if they have heard of the term “set” before and what they think it means. 2. Define a set as a collection of distinct objects or elements. 3. Explain that sets can be represented using set notation, which includes curly braces {} and commas to separate the elements. 4. Provide examples of sets and ask students to identify the elements and describe the sets using appropriate language. 5. Introduce the concept of a universal set, which is a set that contains all the elements under consideration. 6. Discuss the different types of sets, such as finite sets, infinite sets, empty sets, and singleton sets. 7. Explain the concept of a subset, which is a set that contains only elements from another set. 8. Introduce the power set, which is the set of all possible subsets of a given set.

TASKS/ACTIVITIES: 1. Divide the class into small groups and provide each group with a set of objects. 2. Ask each group to list the elements of their set and describe it using appropriate language. 3. Have each group present their set to the class, explaining their choices of elements and how they described the set. 4. Provide examples of Venn diagrams and explain how they can be used to represent sets and their relationships. 5. Give students practice problems involving Venn diagrams and ask them to identify and describe the regions of the diagrams. 6. Introduce the concept of set operations, such as union, intersection, and complement. 7. Use Venn diagrams to illustrate and solve problems involving set operations. 8. Discuss De Morgan’s laws and how they can be applied to sets. 9. Provide examples of problems involving sets of numbers and guide students through the process of solving them.

CLOSURE and plenary: 1. Review the main concepts covered in the lesson, including the definition of a set, set notation, types of sets, universal set, subsets, power set, Venn diagrams, set operations, and De Morgan’s laws. 2. Ask students to share any questions or difficulties they encountered during the lesson. 3. Summarize the key points and reinforce the importance of understanding sets in various mathematical contexts. 4. Assign a homework task that requires students to apply the concepts learned in the lesson to solve problems involving sets.

EVALUATION: 1. Use questioning techniques throughout the lesson to assess students’ understanding of the concepts. 2. Assign a worksheet or set of practice problems for students to complete individually or in groups. 3. Review and provide feedback on students’ work to assess their mastery of the lesson objectives.
