In this lesson on rounding numbers, Professor Perez demonstrates how to round numbers on a number line and how to describe the process using words. Starting with rounding to the nearest 10, then 100, and finally 10,000, Professor Perez highlights the importance of identifying the digit in the place being rounded to and looking at the next digit to determine whether to round up or leave it as is. With helpful examples and explanations, this lesson is perfect for students looking to improve their rounding skills.
