Greatest means the largest number in a group.
Least means the smallest number in a group.
The greatest number has the most value, and the least number has the smallest value.
Place value tells us how much each digit is worth based on where it is in the number. We can look at the digits in the ten thousands, thousands, hundreds, tens, and ones places.
When comparing numbers, always start by looking at the digit in the highest place value first.
To compare numbers, look at each place value from left to right. The number with the larger digit in the first different place is the greater number.
You only need to find the first place where the digits are different to decide which number is greater or least.
To find the greatest and least numbers in a group, compare all the numbers using their place values.
You can write the numbers in order from least to greatest to help find which is smallest and which is largest.
A number line shows numbers in order from least to greatest. Numbers on the left are smaller, and numbers on the right are larger.
Number lines help you see the order of numbers quickly and clearly.
