Conclusion
• Understanding place value can help you compare
and order numbers.
• Start at the far left place value of the numbers,
adding zero(s) as place holders when the numbers
don’t have the same number of place values.
• Compare the digit of each place value where the
digits are different.
• The way those digits compare is the way the
whole numbers compare.
• Use > (greater than), < (less than), or = (equal to)
when comparing numbers.
