Free Online Worksheet to help students practice rounding a multi-digit number to any place value and how to use rounding to estimate and check the answers to word problems.

Objective:

- I know how to round a multi-digit number to any place value and use rounding to estimate and check the answers to word problems.

**How to use estimation or rounding?**

Estimation or rounding is a useful tool for checking answers because it allows you to quickly determine if an answer is reasonable or not.

Here are some steps you can follow to use estimation to check an answer:

**Step 1:** Make sure you understand what you are being asked to find and what information you have been given.

**Step 2:** Round any numbers given in the problem to the nearest whole number, or to the nearest ten, hundred, or thousand, depending on the level of accuracy needed.

**Step 3:** Use mental math to perform calculations quickly. For example, if you need to add 23 and 45, round them both to 20 and 50 and add those instead. This will give you an estimate that is close to the actual answer.

**Step 4:** Once you have an estimate, compare it to the actual answer you calculated. If the estimate is close to the actual answer, you can be confident that your calculation is correct. If the estimate is significantly different from the actual answer, you may need to review your work and make corrections.

By using estimation to check your answers, you can catch errors early and avoid making mistakes that could lead to incorrect results.
