Comparing numbers is an important skill in math, especially for class 2 students. When we compare numbers, we look at two or more numbers and decide which one is greater, smaller, or if they are equal. To compare numbers, we use symbols like the greater than symbol (>), the less than symbol (<), and the equal to symbol (=). For example, if we compare the numbers 45 and 23, we can see that 45 is greater than 23. We write this as 45 > 23. If we compare 12 and 12, they are equal, so we write 12 = 12. If we compare 30 and 50, we see that 30 is less than 50, so we write 30 < 50.
To compare numbers, we start by looking at the digits in each place value. First, we compare the hundreds place, then the tens place, and finally the ones place. For example, let’s compare 345 and 278. The digit in the hundreds place of 345 is 3, and in 278, it is 2. Since 3 is greater than 2, we know that 345 is greater than 278, so we write 345 > 278. If the hundreds digits are the same, we move to the tens place. For example, compare 456 and 472. The hundreds digits are both 4, so we look at the tens place. In 456, the tens digit is 5, and in 472, it is 7. Since 5 is less than 7, we know that 456 is less than 472, so we write 456 < 472. If the tens digits are also the same, we compare the ones place. For example, compare 789 and 785. The hundreds and tens digits are the same, so we look at the ones place. In 789, the ones digit is 9, and in 785, it is 5. Since 9 is greater than 5, we write 789 > 785.
Let’s try another example. Compare 623 and 623. Here, all the digits in the hundreds, tens, and ones places are the same, so the numbers are equal. We write 623 = 623. Comparing numbers helps us understand which number is bigger or smaller and is useful in solving math problems.
Here are some exercises to practice comparing numbers. Compare 345 and 456. Which number is greater? Compare 789 and 789. Are they equal? Compare 123 and 321. Which number is smaller? You can also use worksheets on comparing numbers to practice more. These worksheets have examples like 567 > 345 or 234 < 456. By practicing, you will get better at comparing numbers and using the symbols >, <, and =.
Remember, when comparing numbers, always start from the leftmost digit and move to the right. This will help you find out which number is greater, smaller, or if they are equal. Keep practicing, and soon you will be a pro at comparing numbers!
