Number of elements/cardinality of sets
Teaching steps
1. Design hands on activities to empower students understanding
on how to recognize the cardinality of sets. Assist students
through discussion to derive the general formula by considering
two arbitrary finite sets as shown in Figure 1.10 in the Student’s
Book.
2. Use Examples 1.31 and 1.32 in the Student’s Book to engage
students through discussion to perform calculation on
cardinality of two sets.

3. Assist students through discussion to derive the cardinality of
union of three sets by considering the cardinality of two sets.
Allow students to share alternative methods of deriving the
cardinality of the union of three sets.
