Comparing and Ordering 4-Digit Numbers from Least to Greatest
Title: Learn to Compare 4-Digit Numbers and Put Them in Order!
Introduction: Hey kids! 🌟 Today, we’re going to learn something super fun and useful — how to compare big numbers, like 4-digit numbers, and put them in the right order from least to greatest. Don’t worry, it’s easier than it sounds! Let’s get started.
Step 1: Understanding 4-Digit Numbers
A 4-digit number is any number that has four digits. Here are some examples of 4-digit numbers:
- 2,134
- 7,569
- 1,009
The value of a 4-digit number depends on each digit and its place in the number. For example, in 2,134:
- The first digit (2) is in the thousands place.
- The second digit (1) is in the hundreds place.
- The third digit (3) is in the tens place.
- The last digit (4) is in the ones place.
The higher the digit is in the thousands place, the bigger the number is!
Step 2: Comparing 4-Digit Numbers
Now, let’s learn how to compare two 4-digit numbers. We always start by looking at the thousands place.
Let’s compare 2,134 and 4,567:
- In 2,134, the first digit (thousands place) is 2.
- In 4,567, the first digit (thousands place) is 4.
Since 4 is greater than 2, we know that 4,567 is greater than 2,134.
But what if the thousands digits are the same? Let’s compare 2,134 and 2,452:
- The first digits are both 2, so we move to the next place — the hundreds.
- In 2,134, the hundreds digit is 1.
- In 2,452, the hundreds digit is 4.
Since 4 is bigger than 1, 2,452 is greater than 2,134.
Step 3: Putting Numbers in Order (Least to Greatest)
To put a group of numbers in order, compare each one. Let’s try putting these 4-digit numbers in order:
- 4,512
- 3,678
- 5,234
- 4,120
- First, compare the thousands place:
- 4,512 (thousands digit: 4)
- 3,678 (thousands digit: 3)
- 5,234 (thousands digit: 5)
- 4,120 (thousands digit: 4)
The smallest number here is 3,678 (because 3 is smaller than 4 and 5).
- Now compare the two numbers that have a 4 in the thousands place:
- 4,512 and 4,120.
Since the thousands place is the same, we move to the hundreds place. The hundreds place for 4,512 is 5, and for 4,120 it is 1. Since 1 is smaller, 4,120 comes next.
- Finally, we place the largest number last, which is 5,234.
Now, our order from least to greatest is:
- 3,678
- 4,120
- 4,512
- 5,234
