LESSON 1: SETS We encounter different things in our daily lives. They are of different shapes, colors, sizes, type and classification. These things can be grouped into sets. A set is a group of things put together.
A set of flowers
a set of leaves
The objects in a set are called elements. These elements in a set have their similarities.
A set of circle-shaped things
a set of big animals
An empty set is a set with no elements in it.

LESSON 2: COMPARING SETS Every set may have difference or similarities into another set. We can compare these sets through the number of elements on it. We can use more than or fewer than to compare the number of elements in the set.
There are more boys than girls. The set of boys has more element than the set of girls. The set of girls has fewer elements than the set of boys. We can also use as many as if the sets have the same number of elements.
The two sets have the same number of elements. The set of rabbits is as many as the set of puppies. YOUNG JI INTERNATIONAL SCHOOL/COLLEGE
