These activity sheets will teach your students how to correctly determine the error of estimation.

Estimates are never exact. That is why you almost always going to have some level of error with that measurement. Knowing how far off you are is a bit of an exact science. Which is funny when you think about it. If you would have got the math correct to begin with you would not have to be calculating the level of error that you made. The following worksheets ask your students to estimate answers using rounding, then determine the difference between the estimated answers and the actual answers, which is called the error of estimation. To estimate means to find something close to the exact answer. In these worksheets, your students will learn to estimate by rounding off the values of a given problem and then calculating the answer mentally, without writing the problem down. They will then solve for the exact answer using whatever mathematical operation is required by the question. Finally, they will determine the error of estimation by finding the difference between the estimated result and the exact result. This set of worksheets contains lessons, step-by-step solutions to sample problems, and both simple and more complex problems that students can use for independent practice. When finished with this set of worksheets, students will be able to estimate, then solve for the exact answer and determine the error of estimation. A prior understanding of the concept of rounding is required.

These worksheets explain how to calculate the error of estimation. They also explain how to estimate, then solve for the exact answer and determine the error of estimation. This is a neat way to learn about the concept of errors in measurement.
