Rounding Numbers Concepts

This video tutorial covers fourth-grade module one, lesson nine, focusing on rounding numbers to various place values. It begins with an introduction to rounding to the nearest thousand, using a simulated number line. The lesson progresses to rounding to the nearest ten thousand and hundred thousand, employing standard algorithms and examples. The tutorial concludes with a practical example involving President Obama's 2013 inauguration attendance, illustrating rounding to the nearest hundred thousand.
