Finding the Value of Digits in 5-Digit Numbers

MatholiaChannel

This video serves as a clear, visual introduction to place value in five-digit numbers, specifically focusing on numbers up to 100,000. Using a digital representation of "place value cards," the video demonstrates the difference between a digit and its value based on its position within a number. It walks viewers through three distinct examples, asking them to identify the value of a specific digit within a larger number (e.g., finding the value of 5 in 35,146). The key theme explored is the base-10 number system and the concept of decomposition. The video visually deconstructs standard form numbers into their expanded parts—Ten Thousands, Thousands, Hundreds, Tens, and Ones. By sliding the digit cards apart to reveal the trailing zeros behind each number, it concretely illustrates why a digit in the thousands place represents a value in the thousands rather than just a single digit. For educators, this video provides an excellent visual model for moving students from concrete to abstract understanding of large numbers. The animation of separating the numbers is a powerful tool for explaining "expanded form" without overwhelming students with text. It is particularly useful for 3rd and 4th-grade classrooms as a hook for a lesson on large numbers, a review for struggling students, or a direct instructional tool to pause and predict values during whole-class discussion.
