2nd - 4th Grade

Mathematics

This free printable worksheet helps Grade 2–4 students round whole numbers to the nearest ten. It focuses on using the ones digit to decide whether a number rounds down or up, with examples such as 12 rounding to 10, 85 rounding to 90, and 639 rounding to 640. Students also identify numbers that round to a given multiple of ten and determine which numbers do not belong in a rounding group. The 20-question mathematics set includes 15 multiple-choice items and 5 multiple-select items. Questions range from rounding two- and three-digit numbers, such as 503, to explaining why 12 rounds down based on its ones digit. The varied question types give teachers evidence of both procedural accuracy and students’ understanding of rounding decisions. This free printable worksheet includes a complete answer key for efficient review, independent practice, homework, or formative assessment.

FAQs

What does this worksheet cover, and how does it help students learn to round to the nearest ten?

This worksheet practices rounding two- and three-digit whole numbers to the nearest ten through 15 multiple-choice and 5 multiple-select questions. Students apply the ones-digit rule, handle values such as 25 and 85, round numbers such as 503 and 639, and identify which numbers do or do not round to a target multiple of ten.

How can I use this worksheet to teach rounding to the nearest ten?

Introduce the worksheet by modeling how the ones digit determines whether a number moves down or up to the nearest ten, using examples such as 12, 25, and 85. Then have students explain their choices on the questions that ask which number rounds to a target value or why 12 rounds to 10, using those explanations to connect the rule to the multiple-choice and multiple-select practice.

What mistakes should I watch for when students complete this rounding worksheet?

Watch for students examining the tens digit instead of the ones digit, especially on the question asking why 12 rounds to 10. Students may also select the original number rather than a multiple of ten, confuse nearby choices such as 50 and 60, or overlook the difference between finding a number that rounds to a target and finding one that does not. Three-digit items such as 503 and 639 can reveal whether students apply the same rule consistently across place values.

How do I assign and grade this rounding worksheet?

The worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key for all 20 rounding-to-the-nearest-ten items. For printable submissions, scan student work with the Wayground for Teachers app to help grade responses efficiently.

How can I differentiate this rounding worksheet for my students?

Use the worksheet’s Advanced Settings to adjust font spacing or font size so the multiple-choice and multiple-select rounding items are easier to read and navigate. You can also apply a dyslexia-friendly font or translate the worksheet into another language when that better supports access to the rounding instructions and answer choices.
