Understanding Value Representation in Numbers

The video tutorial introduces the concept of using cubes to represent numbers up to 999. It explains the use of 'shorts', 'longs', and 'flats' to denote units, tens, and hundreds, respectively. Through examples, it demonstrates how to write numbers using these blocks and how to order numbers from smallest to largest. The tutorial emphasizes understanding place value and the importance of each digit's position in a number.
