In these worksheets, students will learn to round and estimate numbers to the nearest ten, hundred, and thousand.

Rounding off numbers is something students are made to learn at a very early stage in mathematics. This is because it is crucial to understand the concept as they might need to solve problems that involve rounding off numbers. Rounding means to make a number simpler while keeping its value near or close to the real/exact value. For example, number 73 is rounded off to the number 70, and number 76 is rounded off to the number 80. The number becomes less accurate but easier to use. Similarly, if you have the number 0.1, the number is less than five, so you will round it off to 0, and if you have 0.9, the number is greater than 5 you will round it off to 1. It is important to note that in rounding off, you consider the number lesser or greater than 5 and then round it off accordingly. Rounding off is further categorized into rounding up and rounding down. Rounding up means even if the number is less than 5, say 0.1, you still round it up and make it 1. This is most common in cases when the event involves money. And rounding down means even if the number is 0.9, round it down to 0. This is understandable in situations when you are counting people to fit on a ride if half of a person can fit on the ride, but the other half cannot.; the whole person doesn't fit. And hence the person is eliminated from the count.

Rounding a number up or down means to make the number simpler, while still keeping its value close to what it was. Though a "round number" is less accurate, it is easier to use. In these worksheets, students will practice rounding numbers. They will round numbers to the nearest whole ten, hundred, and thousand, as well as to the nearest tenth, hundredth, and thousandth decimal place. In some problems, they will use number lines for reference. Some problems involve negative numbers. This set of worksheets contains step-by-step solutions to sample problems, both simple and more complex problems, a review, and a quiz. It also includes many worksheets that students can use to practice independently. When finished with this set of worksheets, students will be able to round and estimate numbers to the nearest ten, hundred, and thousand. These worksheets explain how to round and estimate numbers to the nearest ten, hundred, and thousand. Sample problems are solved and practice problems are provided.
