The video tutorial explains how to round numbers to the nearest whole number or one's place value. It uses a number line to illustrate how numbers closer to five round down, while those closer to six round up. Examples such as 5.7, 5.2, and 5.5 are used to demonstrate the rounding process. The general rule is to look at the digit in the tenth place: if it's four or less, round down; if it's five or more, round up.
