These worksheets introduce concepts related to precision and uncertainties in measuring length. Precision is related to the smallest divisions on the measuring device (a ruler with divisions of 1/16th of an inch is more precise than a ruler with 1/4" divisions). Uncertainties are related to the natural error in any physical measurement ("plus or minus 1/8").
Browse all of our measurement worksheets, from"bigger vs smaller" to the measurement of length, weight, capacity and temperature in customary and metric units.
