Rounding Numbers and Rules

The video tutorial explains a special case in rounding numbers, focusing on a scenario where a digit exceeds its place value. The instructor guides through the process of setting up the number, identifying the ones place, and handling the situation where a two-digit number results from rounding. The tutorial concludes with finalizing the rounding and explaining the importance of zeros in the result.

What is the first step in the rounding process described in the video?

• Circle the number to be rounded

• Draw an arrow to the next digit

• Write the number on a chart
