Rounding to the Nearest 10 with a Carry in Many Places

This lesson teaches how to round whole numbers to the nearest ten, especially when multiple carries are involved. It provides two examples: rounding 2999 to 3000 and 199,995 to 200,000, demonstrating the process of carrying over digits. The lesson concludes with a summary of the rounding process for multidigit numbers.

What is the first step in rounding a number like 2999 to the nearest ten?

• Look at the tens digit

• Look at the ones digit

• Look at the hundreds digit

• Look at the thousands digit

When rounding 2999 to the nearest ten, what happens after increasing the tens digit by one?

• The ones digit is increased by one

• The hundreds digit is decreased by one

• The number remains unchanged

• The tens digit becomes zero and a carry is added to the hundreds place

In the example of rounding 199,995, what is the result after rounding?

• 199,900

• 200,000

• 199,990

• 199,999

What happens to the digit in the ones place when rounding 199,995 to the nearest ten?

• It becomes one

• It becomes zero

• It remains five

• It becomes nine

What is the key takeaway from the lesson on rounding multidigit numbers?

• Rounding is only necessary for numbers above 1000

• Rounding does not require carrying over

• Rounding is only applicable to even numbers

• Rounding to the nearest ten often involves carrying over in multiple places
