Ordering numbers means arranging numbers from least to greatest or from greatest to least. This helps us compare the size of large numbers and understand their value.
When numbers get big, it is even more important to look carefully at each place value before deciding which is larger or smaller.
To identify the order of numbers, compare digits from left to right, starting with the largest place value. For big numbers, this means starting with the hundred thousands place.
Work slowly from left to right. Each place value tells you more about the number’s size.
Here are some examples that show how to order larger numbers correctly.
Remember: the largest digit in the highest place value decides which number is greater.
A number line can also show the order of big numbers. Just like with small numbers, numbers to the left are smaller, and numbers to the right are larger.
Using number lines for large numbers helps you “see” the difference, especially when the digits look similar.
