A student estimates the sum of 2,879 and 3,214 by rounding to the nearest hundred. Show the rounding and the estimate sum

2,800 and 3,200 = 6,000

500

Explain why 5,500 rounds to 6,000 when rounding to the nearest thousand, but rounds to 5,500 when rounding to the nearest hundred 

To round to the nearest thousand, look at the hundreds digit; the 5 rounds up to 6,000. To the nearest hundred, look at the digit in the tens place; since it is 0, it stays at 5,500
