Understanding Place Value Concepts

This video tutorial by Margo Poro from the Western Canadian Learning Network explains the concept of place value, demonstrating how any number can be constructed using ten digits (0-9). It covers the arrangement of digits into periods (units, thousands, millions, billions) and highlights the international differences in number formatting, such as the use of spaces instead of commas. The tutorial uses examples to show how each digit's position affects its value, emphasizing the importance of zeros as placeholders. A place value chart is used to further illustrate these concepts with large numbers.
