Place Value Topic Guide

Understanding how place value works is a fundamental concept in mathematics. It is crucial in calculations to understand what the value of each digit within a number is.

Our base-10 number system means that the value of a digit is determined by its place within the number.

Number Facts

  • The decimal place value system is based on the number 10.
  • Place value allows you to write any number, no matter how big or small, using only the digits 0-9!
  • Place value tells us how much each digit in a number is worth. For example, the digit 8 could represent 8 tens (in 86) or 8 thousands (in 8734).
  • In any number, whole numbers are placed to the left of the decimal point, and fractions of numbers to the right of it. For example, in 1.5 the 1 represents 1 whole, and the 5 represents 5/10, or 1/2.
  • Place value systems were developed by several early civilisations, including the Babylonians. The system we use started in India and started to spread across the world in the 8th century.
