Understanding Place Value with 4-Digit Numbers

MatholiaChannel

This educational video provides a clear, step-by-step introduction to place value for 4-digit numbers, specifically focusing on thousands, hundreds, tens, and ones. Using the Concrete-Pictorial-Abstract (CPA) pedagogical approach, the video guides viewers through recognizing the value of each digit within a larger number. It transitions from concrete visual aids like base-10 blocks to representational tools like an abacus, and finally to abstract numerical breakdowns using expanded form. The video explores key mathematical themes including digit value versus place value, decomposing numbers into their constituent parts (expanded form), and reading 4-digit numbers. It explicitly demonstrates how a digit's position determines its quantitative value—showing, for instance, that a '5' in the thousands place is vastly different from a '5' in the tens place. The examples cover numbers such as 1,463, 8,590, 5,698, and 1,357. For educators, this resource is an excellent visual anchor for introducing or reinforcing number sense in lower elementary grades. It is particularly useful for helping students visualize the magnitude of numbers and understanding the structure of the base-10 system. The clear pacing allows teachers to pause and ask students to predict values before they are revealed, making it a versatile tool for whole-class instruction, remediation, or independent review centers.
