Whole numbers are numbers that start from zero and continue counting upwards without any decimal or fraction parts. They are used for counting whole objects like apples, pencils, or people.
Imagine you have 3 apples. The numbers you use to count the apples are whole numbers. They are 1, 2, 3, 4, and so on.
If you have 2 pencils and you get 3 more, you can add them together using whole numbers. For example:
$$
2 + 3 = 5
$$
When you have 5 friends and 2 of them leave, you can subtract using whole numbers. For example:
$$
5 - 2 = 3
$$
Counting Game:
Gather some objects like stones, toys, or buttons. Ask a friend to close their eyes while you hide some of the objects. Let them open their eyes and guess how many are hidden. Use whole numbers to count and check the answer together.
