Hello, young learners! Welcome back to our mathematics lesson for this week. Mathematics is a crucial subject that helps us understand and navigate the world around us. In our previous lesson, we learned about No previous lesson found.. Today, we’re going to learn about whole numbers, specifically numbers from 1 to 200. This is an important foundation for many aspects of mathematics, including counting, addition, subtraction, and more.

### Objectives

By the end of this lesson, you should be able to:

- Identify numbers from 1 to 200.
- Read numbers from 1 to 200.
- Write numbers from 1 to 200.
- Order numbers from 1 to 200.
- Write numbers from 1 to 200 in words.

### Whole Numbers 1 – 200

Whole numbers are the basic building blocks of mathematics. They include all positive numbers without any fractions or decimals.

#### What are Whole Numbers?

Whole numbers are the numbers we use for counting. They start with 0 and continue infinitely. Some of the whole numbers include: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and so on.

#### Understanding Whole Numbers

There are several ways to understand whole numbers:

**Counting Objects:**We can use whole numbers to count objects, such as apples, books, or people. For example, if we have 5 apples, we can represent this with the whole number 5.**Number Line:**A number line is a visual representation of whole numbers. It helps us see the order of numbers and their relative positions. The number line starts with 0 and continues to the right, with each number representing a point on the line.**Place Value:**Each digit in a whole number has a specific place value. For example, in the number 123, the digit 1 is in the hundreds place, the digit 2 is in the tens place, and the digit 3 is in the ones place.

#### Identifying Numbers

Identifying numbers involves recognizing the symbols that represent each number. This is important for reading and writing numbers correctly.

Examples:

- 1: One
- 2: Two
- 10: Ten
- 50: Fifty
- 100: One hundred

#### Reading Numbers

Reading numbers correctly is essential for understanding mathematics. When we read numbers, we say them in a way that helps us recognize their value.

Examples:

- 1: One
- 25: Twenty-five
- 75: Seventy-five
- 150: One hundred and fifty

#### Writing Numbers

Writing numbers helps us communicate mathematical ideas clearly. It is important to write numbers neatly and correctly.

#### Ordering Numbers

Ordering numbers means arranging them in a sequence. This can be from the smallest to the largest (ascending order) or from the largest to the smallest (descending order).

Examples:

- Ascending Order: 1, 2, 3, 4, 5, …
- Descending Order: 200, 199, 198, 197, …

#### Writing Numbers in Words

Writing numbers in words helps us understand how numbers are spelled and pronounced. This skill is useful in many areas of life.

Examples:

- 1: One
- 2: Two
- 10: Ten
- 50: Fifty
- 100: One hundred
- 150: One hundred and fifty
- 200: Two hundred

### Evaluation Questions

Now that you’ve learned about whole numbers from 1 to 200, let’s see if you can answer these questions:

- What is the smallest whole number? 2. What is the largest whole number between 1 and 200? 3. Write the number 125 in words. 4. Order the following numbers from smallest to largest: 100, 50, 150, 200, 1. 5. What is the place value of the digit 3 in the number 135?

### Conclusion

Today, we learned about whole numbers from 1 to 200. We explored how to identify, read, write, and order numbers. These skills are fundamental to understanding and using mathematics in everyday life. Keep practicing, and don’t hesitate to ask questions if you have any.
