Key Vocabulary in Place Value

Estimate: A number that is nearly equal to the exact amount, useful for quick calculations.
Expanded Form: A method of displaying numbers that emphasizes the value of each digit, illustrating their contribution to the overall number (e.g., 345 = 300 + 40 + 5).
Period: Refers to groups of three digits in multi-digit numbers, which are separated by commas to enhance readability (e.g., in 1,234,567, the periods are 567, 234, and 1).
Rounding a Number: The process of adjusting a number to a nearby value that provides a reasonable approximation, making calculations simpler.
Standard Form: The conventional way of writing numbers using digits from 0 to 9, where each digit's position determines its value (e.g., 257 is in standard form).
Word Form: A representation of numbers using words instead of digits, maintaining the value of each digit (e.g., 257 is written as "two hundred fifty-seven").
Order Numbers: The specific arrangement of numbers in a sequential manner, whether ascending or descending.
Compare: The act of evaluating two or more numbers to determine their relationships, indicating whether they are equal, greater, or less than one another.
Place Value: The importance of a digit in a number, determined by its position, which directly influences the digit's overall contribution to the total value of the number (e.g., in 432, the 4 is worth 400).
