Let's practice rounding up or down! Look at each number and round it to the nearest one, ten, hundred, or thousand, according to the directions. Use a number line or place-value chart to help you. Type the correct answer in the box, and check to see if you are correct!
Round to the nearest ten.
Use the number line to round 43 to the nearest ten.
That's right!
Incorrect. To use the number line to round, find the number 43 on the number line and look to see which ten it is closer to, 40 or 50. 43 is closer to 40, so we round down.
Round to the nearest hundred.
Use the place-value chart to round 463 to the nearest hundred.
You got it!
Incorrect. To round to the nearest hundred, look to the place to the right of the hundreds place. The tens place has a 6. Our rounding rule says that if the digit to the right is 5 or above, we round up. 463 would round up to 500.
Round to the nearest thousands.
Use a place-value chart to round 6,499 to the nearest thousand.
Well done!
Incorrect. To round to the nearest thousand, we look to the place to the right of the thousands place. In the hundreds place, there is a 4. Our rounding rule says if the digit to the right is 4 or below, we round down. That means we round this number down to 6,000.
Round to the nearest hundred.
Use a place-value chart to round 4,520 to the nearest hundred.
That's correct!
Incorrect. To round to the nearest hundred, look to the place to the right of the hundreds place. The tens place will tell us to round up or down. Our rounding rule says if the digit to the right is 4 or below, we round down. There is a 2 in the tens place, so we round the hundreds place down. Our answer is 4,500.
Round to the nearest ten thousand.
Use the place-value chart to round 56,837 to the nearest ten thousand.
You got it!
Incorrect. Look at the digit in the place to the right of the ten thousands. We will use the thousands place to help us round. Our rounding rule says if the digit is 5 or above, we round up. That means the 5 in the thousands place rounds up to 6. Our answer is 60,000.
