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

• Identify the place value to round to

Why is the number 9 considered a special case in this rounding example?

• Because it is a prime number

• Because it is the lowest single-digit number

• Because it is an even number

• Because it is the highest single-digit number

What rule is applied when the digit next to the one being rounded is 5?

• Round down

• Round up

• Ignore the digit

• Keep the same

What happens when you round up from 9?

• It stays 9

• It becomes 0

• It becomes 11

• It becomes 10

How do you handle a two-digit result when rounding up from 9?

• Write both digits in the same place

• Round down instead

• Ignore the second digit

• Spread the digits across two place values

What does the 9 do when it 'moves over' to the 7?

• It increases the 7 by one

• It stays the same

• It decreases the 7 by one

• It replaces the 7

What does the 0 from the 10 replace in the final number?

• The 7

• The 9

• The 5

• The 1

Why is it important to write the zero in the final rounded number?

• To ensure the value is correct

• To follow rounding rules

• To make the number look bigger

• To differentiate between similar numbers

What happens to the digits after the circled number in the rounding process?

• They are added to the final number

• They are ignored

• They become zeros

• They are subtracted from the final number

What is the final rounded number in the example?

• 70

• 100

• 80

• 90
