How do you determine which of two multi-digit whole numbers has the greatest value?
Press to flip
Line up their number places starting with the ones place and compare the digits from left to right, starting with the largest number place.
What is the first step in comparing two multi-digit numbers?
Press to flip
Line up their number places, starting with the ones place digits, which are farthest to the right.
How do you compare the digits of two numbers?
Press to flip
Start with the digits farthest to the left in the largest number place and compare them.
What happens if the digits in the largest number place are the same?
Press to flip
Shift one number place to the right and compare the next largest number place digits.
Using the example of 329 and 495, which number is larger and why?
Press to flip
495 is larger than 329 because 4 in the hundreds place is greater than 3 in the hundreds place.
How do you determine which number is larger if their largest place digits are the same?
Press to flip
Compare the next largest place digits until a difference is found.
Using the example of 856 and 842, which number is larger and why?
Press to flip
856 is larger than 842 because 5 in the tens place is greater than 4 in the tens place.
What if two numbers have the same initial two digits?
Press to flip
Compare the ones-place digits to determine which number is larger.
Using the example of 249 and 246, which number is larger and why?
Press to flip
249 is larger than 246 because 9 in the ones place is greater than 6 in the ones place.
What should you do if the numbers you’re comparing have different amounts of digits?
Press to flip
The number with more digits is greater.
Using the example of 75 and 128, how can you tell which is larger?
Press to flip
128 is larger than 75 because it has a digit in the hundreds place.
What hypothetical digit can you imagine for comparison in numbers with different digit counts?
Press to flip
Imagine a zero in the missing high place digit for the shorter number.
In the example of 134,297 and 137,499, which number is larger and why?
Press to flip
137,499 is larger because the 7 in the thousands place is greater than the 4 in the thousands place.
What general rule can be used to compare numbers of different lengths?
Press to flip
The number with more digits is greater.
What should you do if there's a tie in one number place?
Press to flip
Move to the next largest number place and compare those digits.
How can practice help with comparing multi-digit numbers?
Press to flip
With practice, you can quickly learn to compare numbers just by looking at them.
