Ordering numbers means arranging numbers from least to greatest or from greatest to least. It helps us compare values and understand number size up to 1,000.
When we order numbers, we compare their place values: hundreds, tens, and ones.
To find out which number is greater or smaller, compare the digits starting from the left: hundreds first, then tens, then ones.
Always start comparing with the greatest place value (hundreds) before moving to smaller place values.
When ordering three or more numbers, compare them one step at a time until they are all in order.
Writing numbers in order helps with comparing, adding, and subtracting later.
A number line is a visual tool that shows numbers in order. Numbers to the left are smaller, and numbers to the right are greater.
Number lines make it easier to see the order of numbers without comparing digits one by one.
