Estimating Units of Length Worksheets

Students learn how to estimate length with this collection of worksheets. Tips for Estimating Units of Length- Distance and lengths can be estimated by using the method of approximation for measurements. For instance, one meter is less the distance between your shoulder to fingertips, if you the hand is all stretched out. One meter is also the distance of one long jump or large step. Estimation is used when the measuring tools are not nearby or are not available, and you need a value to make an approximate assumption. Remember, approximation doesnâ€™t give you the exact value but a close number. Another tip for estimating length is through comparison if object A is 40 cm and object B is double in size of the length of A. Then, without using any measuring instrument, we can say that length of B is (A x 2) = 80cm. Tip number 3 is using objects whose size is known to measure other objects. For example, if you have a box of match sticks and every match is 2 inches, then you can measure any object in inches using matches. It can give you a closer to the perfect measurement of any object in the proximity.
