This first lesson is more of an introductory lesson to Sets.
During previous grades, we learned about the basic idea of a set and know how to work with them. We learnt three basic methods.
- Descriptive method
- This is very easy. It's just describing what a set is in words.
A = \( \{\text{even numbers between 0 and 10} \} \)
- Method of listing elements
- Also called the roaster method, this is just listing out the elements in a list.
\( A = \{2, 4, 6, 8\} \)
- Venn Diagram method
- Venn diagrams can visualize your sets, and we learnt only a little bit about those. Well it's going to get even more interesting!

So let's take a look at a new method to describe sets - the set builder method. Watch the below video!
Practice Time! Follow the below video to learn how to define sets in all the different ways that we learnt.
