Compare and Order Whole Numbers to 100: When Students Ask

  • Why should I learn the facts?
    Knowing the order of numbers and knowing which numbers are greater than or less than other numbers can help you in everyday situations. For example, if you are buying a pencil, you can tell if the number of pennies that you have is more than or less than the number of pennies that is needed to buy the pencil. Or, if you are number 12 in a race, you can listen to the numbers and know when it is your turn to race.
  • How can I remember what > and < mean?
    Tell children that the large open end points to the larger or greater number and the small closed end points to the smaller or lesser number.
  • How do I know when one number is greater than another number?
    If one number has more tens, that number is greater. If both numbers have the same number of tens, compare the ones to see which has more.
  • How do I know when one number is less than another number?
    If one number has fewer tens, that number is less. If both numbers have the same number of tens, compare the ones to see which has fewer ones.
