Sixteen numbers to round: eight to the nearest 10 on the left and eight to the nearest 100 on the right. Look at the digit just to the right of the place you are rounding to: 5 or more rounds up, 4 or less rounds down, so 275 rounds to 280 and 349 rounds to 300. Each column has at least one halfway number, the ones most children get wrong.
