Math is very challenging as a subject and there are tons of mistakes that we make while solving questions. On top of that, there are various terms, definitions, word problems, questions and operations that require carefully looking at the questions and then solving them, one by one. There are a variety of questions we come across every time we are doing math, and today we are going to take a look at something new. Now, do you know what estimation is? Let's find out! To estimate means to find something close to the exact answer. Estimation is a rough idea of what the value is equal to without having a proper idea of the number. Estimation requires operating mentally, and often there is no need to get an exact result, instead only an idea or an estimate is required of the outcome. Just like any other question, estimation too, requires concentration and attention to solve. And there are several mistakes one can make during estimation. Here are a few; Copying the problem incorrectly. Writing the wrong number. Sloppy handwriting. Dropping a negative sign. Unable to follow directions. Working slowly. Unclear concepts.
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 estimate, then solve for the exact answer and determine the error of estimation. Sample problems are solved and practice problems are provided.
