1. Counting Numbers: These are the numbers you use for counting things like apples, toys, and fingers. They start with 1 and go on forever: 1, 2, 3, 4, and so on.
2. Whole Numbers: Whole numbers include counting numbers along with the number 0. So, it’s like having all the numbers you use for counting plus the number 0: 0, 1, 2, 3, and so forth.
3. Integers: Integers are like whole numbers, but they can also have negative values. So, you have numbers like -3, -2, -1, 0, 1, 2, 3, and so on. They include positive numbers, negative numbers, and zero.
4. Rational Numbers: These are numbers that can be written as fractions. Fractions are like pieces of something, for example, 1/2, 3/4, and even whole numbers like 5 can be written as 5/1. So, any number that can be a fraction is a rational number.

5. Irrational Numbers: These are a bit trickier. They are numbers that can’t be written as fractions. One famous irrational number is pi (π), which is about 3.14159… and it goes on forever without repeating. Another is the square root of 2 (√2), which is around 1.41421… and also doesn’t end or repeat.
6. Real Numbers: Real numbers are like a big family that includes all the numbers we talked about before: counting numbers, whole numbers, integers, rational numbers (fractions), and irrational numbers (like pi and the square root of 2). In simple words, if a number exists on a number line, it’s a real number.
