Let’s learn how to compare whole numbers using some special symbols:
When we compare two numbers, we look at the biggest place value first. Let’s see how it works with some examples:
Look at the tens place:
Look at the hundreds place:
Look at the tens place:
Look at the hundreds place:
If the biggest place value is the same, we look at the next place value:
Look at the tens place:
Look at the hundreds place:
Look at the hundreds place:
If all the numbers are the same, we use the equal to symbol:
If the numbers have different place values, the number with the higher place value is greater:
Now you know how to compare whole numbers using these symbols. Keep practicing, and you’ll get even better at it!
Number Hunt: Go on a number hunt around your home or classroom. Find different numbers on items like books, clocks, or calendars. Write down two numbers you find and compare them using the greater than, less than, or equal to symbols. Share your findings with a friend or family member and explain why one number is greater, less, or equal to the other.
Number Line Adventure: Draw a number line on a piece of paper or use a ruler as a number line. Pick two numbers between 1 and 100 and place them on the number line. Use the greater than, less than, or equal to symbols to compare the numbers. Discuss with a partner why the number on the right is greater than the number on the left.
Place Value Puzzles: Create your own number puzzles by writing down two numbers with missing digits (e.g., 3_5 and 3_9). Ask a friend to fill in the blanks with numbers that make one number greater than, less than, or equal to the other. Swap puzzles with a friend and solve each other’s puzzles, explaining your reasoning.

**Comparing Whole Numbers**
To compare whole numbers, we use one of three symbols:
– The greater than symbol (>) means “greater than” or “more than.”
– The less than symbol ( 12.
Now, let’s compare 245 and 137:
– The highest place value is in the hundreds column.
– Since 2 (in 245) is greater than 1 (in 137), we conclude that 245 is greater than 137.
– Thus, we write: 245 > 137.
Next, we compare 10 and 25:
– The first number is 10, and the second number is 25.
– Since 1 (in 10) is less than 2 (in 25), we conclude that 10 is less than 25.
– Therefore, we write: 10 < 25.
Now, let's compare 389 and 456:
– The highest place value is in the hundreds column.
– Since 3 (in 389) is less than 4 (in 456), we conclude that 389 is less than 456.
– Thus, we write: 389 41.
Now, let’s compare 346 and 379:
– The highest place value is in the hundreds column.
– Since 3 (in both numbers) is the same, we look to the tens column.
– Since 4 (in 346) is less than 7 (in 379), we conclude that 346 is less than 379.
– Thus, we write: 346 502.
If the numbers in all of the place values are the same, we use the equal to symbol.
For example, comparing 35 and 35:
– Since both digits are the same, we conclude that 35 is equal to 35.
– Thus, we write: 35 = 35.
Now, let’s compare 412 and 412:
– Since all digits are the same, we conclude that 412 is equal to 412.
– Therefore, we write: 412 = 412.
If the numbers have different place values, the number with the higher place value is greater.
For example, comparing 145 and 42:
– The first number has a hundreds column, while the second number does not.
– Therefore, we conclude that 145 is greater than 42.
– Thus, we write: 145 > 42.
Finally, let’s compare 76 and 100:
– The second number has a hundreds column, while the first number does not.
– Therefore, we conclude that 76 is less than 100.
– Thus, we write: 76 < 100.
