line. Ask them through discussion to explore more on
representation of sets on a number line using mathematics
software such as Symbolab, GeoGebra, or reference books.

2. Use Table 1.1 in the Student’s Book to assist students through
discussion to identify forms of interval on representation of
sets on a number line.
3. Use Examples 1.24 to 1.26 in the Student’s Book to guide
students through discussion to represent sets on a number line.
4. Assign the students to attempt Exercise 1.4 in the Student’s
Book. Advise students to submit their work, check the
correctness of their answers and provide constructive
feedback. Encourage students to explore additional resources,
such as online tutorials, or reference books, to enrich their
understanding and practice further.
