Round to the given place: 256,035 (thousands)

256,000. The 6 is in the thousandths place, and since the 0 in the hundredths place is less than 5, you do not round up, keeping the 256,000 as opposed to 257,000.

So,

When rounding to the nearest thousand, look at the number in the hundreds place. If it is greater than or equal to 5, round up. If not, round down.

256,035

The hundreds place is less than 5, so we round down.

256,035 - - > 256,000
