# Round to the Nearest Ten

- 3rd Grade MathIn the third grade, students need to use estimation to verify the results of mathematical procedures, like addition and subtraction. Proficiency in rounding numbers comes in handy, when they start using estimation techniques. The key idea is to round off numbers to those numbers that are simpler to deal with, so that a quick mental calculation can be performed. For example, students should be able to mentally figure out that 37 + 49 is close to 90, as 37 is close to 40 and 49 is close to 50. **Round to the Nearest Ten Worksheet** helps students to practice rounding off numbers to the nearest ten and to the nearest hundred.
