Chances are your child knows how to round, but has he ever tried rounding to the nearest inch? Similar to rounding to the nearest ten or hundred, you round up if the length is past the halfway mark and down if it isn't. This worksheet helps kids tackle this concept by asking them to measure each thing, then round the length to the nearest inch. Not only is this exercise good rounding practice, it's good ruler practice, too.
