Understanding Place Value Concepts

Mariella from Math Tech Connections introduces a place value chart tool that helps explore the value of digits in numbers. The tool allows users to click through a chart to reveal place values and discuss patterns. It includes an editable feature for building numbers and understanding relationships between digits, such as how the value of a digit changes based on its position.
