When we look at the operation of division, when it comes to estimation, I often feel it is a way to cheat the system. When we are given two values that are going to give us a nasty remainder for certain, you can easily estimate values that will help you bring balance back to the system. We try to encourage students to check or test their values by performing the operation quickly. Estimate the quotient of a division equation by rounding the divisor or dividend.

These worksheets explain how to estimate the value of quotients by rounding factors up to the nearest ten.
