      Things that are arranged following a rule or rules

    • sum -

      The answer in an addition problem

    • difference -

      The answer in a subtraction problem

    • symbols -

      An image used instead of words

    • expanded form -

      A number written as the sum of the values of its digits (a way of writing numbers to show place value)

    • regrouping -

      To name a whole number in a different way

    • word form -

      A number written in words

    • equation -

      A number sentence that says two expressions are equal

    • estimate -

      To give an approximate number or answer

    • equality -

      Having the same amount or value

    • rounding -

      Replacing a number with a number that tells about how many or how much to the nearest ten, thousand, and so on

    • place value -

      The value given to the place a digit has in a number

    • compare -

      To decide if one number is greater than or less than another number; or equal to

    • inequality -

      A number sentence that uses < (less than) or > (greater than)
