Understanding Three Digit Numbers
Three-digit numbers are an essential concept in mathematics, and comparing them is a crucial skill for students to master. In this worksheet, we will explore the concept of three-digit numbers, learn how to compare them, and provide exercises to help reinforce understanding.
What are Three Digit Numbers?
Three-digit numbers are numbers that have three digits or places. The first digit is the hundreds place, the second digit is the tens place, and the third digit is the ones place. For example, in the number 456, 4 is in the hundreds place, 5 is in the tens place, and 6 is in the ones place.
How to Compare Three Digit Numbers
Comparing three-digit numbers involves looking at the digits in each place value and determining which number is greater or lesser. Here are the steps to follow:
- Start by comparing the hundreds place. If one number has a greater digit in the hundreds place, it is greater than the other number.
- If the hundreds place is the same, compare the tens place. If one number has a greater digit in the tens place, it is greater than the other number.
- If the tens place is the same, compare the ones place. If one number has a greater digit in the ones place, it is greater than the other number.
đź“ť Note: When comparing three-digit numbers, it is essential to line up the numbers correctly, with the hundreds place, tens place, and ones place aligned.
Examples of Comparing Three Digit Numbers
- Compare 456 and 432:
- Hundreds place: 4 = 4
- Tens place: 5 > 3
- Since the tens place is greater, 456 is greater than 432.
- Compare 945 and 951:
- Hundreds place: 9 = 9
- Tens place: 4 < 5
- Since the tens place is lesser, 945 is lesser than 951.
Exercises
Compare the following three-digit numbers:
- 234 and 219
- 567 and 563
- 943 and 956
- 135 and 149
- 753 and 736
Answers:
- 234 > 219
- 567 > 563
- 943 < 956
- 135 < 149
- 753 > 736
Worksheets
Here is a worksheet with exercises to help you practice comparing three-digit numbers:
| Number 1 | Number 2 | Compare |
|---|---|---|
| 457 | 463 | |
| 942 | 958 | |
| 135 | 148 | |
| 753 | 739 | |
| 627 | 634 |
Fill in the “Compare” column with the correct symbol (> or <) to show which number is greater or lesser.
Conclusion
