Exploring Place Value Concepts in 2nd Grade Math

In this video tutorial, Alexis introduces the concept of place value, explaining how the position of a digit in a number determines its worth. Using blocks, Alexis demonstrates how ones cubes, ten rods, and hundred flats represent different place values. The tutorial includes practical examples at an airport and a parking lot to illustrate the application of place value in real-life scenarios. The video concludes with a recap of the key concepts learned, emphasizing the importance of understanding place value in mathematics.
