Basic set operations
Teaching steps
1. Design hands on activities that allow students to recognize the
basic set operations.
2. Guide students through discussion to recognize the basic set
operations namely, union of sets, intersection of sets, complement
of a set, difference of sets, and symmetric difference.
3. Ask students to explore more on basic set operations from
additional resources such as online tutorial or reference books to
foster their understanding and further practice.
4. Use Examples 1.14 to 1.23 in the Student’s Book to guide students
through discussion to practice basic sets operations.
5. Assign students to attempt Exercise 1.3 in the Student’s Book.
Advise students to submit their work, check the correctness of
their answers, and provide constructive feedback. Encourage
