To round a number to the nearest thousand, you look at the hundreds place. If the hundreds place is 5 or greater, you round up by increasing the thousands place by 1 and replacing all digits to the right with zeros. If the hundreds place is less than 5, you simply replace all digits to the right with zeros. For example, to round 6,784 to the nearest thousand, you would look at the hundreds place (8), which is greater than 5, so you round up to 7,000.
