Lesson 1: Introduction to Sets and Set Relations
Objective: Students will understand the basic concepts of sets, set relations, and the use of Venn diagrams.
-
Engage: Begin the lesson by asking students to brainstorm different categories or groups they belong to (e.g., sports teams, clubs, hobbies). Write their responses on the board.
-
Explore: Introduce the concept of sets by explaining that a set is a collection of objects or elements that share a common characteristic. Use examples from the brainstorming activity to create sets on the board (e.g., Set A: Students who play soccer, Set B: Students who play basketball).
-
Explain: Teach students about set notation and set relations. Explain that sets can be represented using braces { }, and set relations can be represented using symbols such as ⊂ (subset), ∩ (intersection), and ∪ (union). Provide examples and explain the meaning of each symbol.
-
Elaborate: Divide students into pairs or small groups. Give each group a set of objects (e.g., colored blocks, playing cards) and ask them to create their own sets based on a specific characteristic (e.g., Set C: Red objects, Set D: Even-numbered cards). Have them represent the sets using set notation and discuss the set relations between their sets.
-
Evaluate: Provide students with a worksheet containing various sets and ask them to identify the subsets, intersections, and unions. Review their answers as a class.
-
Extend: Introduce Venn diagrams as a visual representation of sets and set relations. Show a video resource like “Introduction to Venn Diagrams” (https://www.youtube.com/watch?v=4q2qOc9jclw) to reinforce the concept.
-
Apply: Assign word problems that integrate algebra and intersectionality. For example: “In a survey, 60% of students play a musical instrument, and 40% play a sport. If 20% of students play both a musical instrument and a sport, what percentage of students do not participate in either activity?”

Lesson 2: Operations on Sets and Intersectionality
Objective: Students will learn about operations on sets, including complement, intersection, and union, and apply these concepts to real-life scenarios involving intersectionality.
-
Engage: Begin the lesson by discussing the concept of intersectionality and its importance in understanding social justice issues. Ask students to share examples of intersectionality they have observed or experienced.
-
Explore: Review the operations on sets, including complement, intersection, and union. Explain that the complement of a set contains all the elements that are not in the original set. Use examples to illustrate each operation.
-
Explain: Introduce the concept of intersectionality in the context of sets. Explain that intersectionality recognizes that individuals can belong to multiple social groups simultaneously, and their experiences are shaped by the intersections of these identities.
-
Elaborate: Provide students with a set of word problems that involve operations on sets and intersectionality. For example: “In a school, 60% of students are girls, 40% are boys, and 20% are both girls and members of a minority group. What percentage of students are girls who are not members of a minority group?”
-
Evaluate: Have students work in pairs or small groups to solve the word problems. Review their solutions as a class, emphasizing the application of operations on sets and intersectionality.
-
Extend: Show a video resource like “Intersectionality Explained” (https://www.youtube.com/watch?v=ViDtnfQ9FHc) to deepen students’ understanding of intersectionality and its relevance in society.
-
Apply: Assign a project where students analyze a real-life scenario involving intersectionality and create a Venn diagram to represent the different social groups involved. They should also write a reflection on how intersectionality impacts the experiences of individuals in that scenario.
