This Grade 3 mathematics worksheet gives students focused practice rounding whole numbers to the nearest 100. It contains 10 multiple-choice questions spanning two-digit and four-digit numbers, including values below 100, three-digit values, and numbers in the thousands. Students select the closest hundred across examples such as 125, 750, 963, 3,210, and 4,587. The worksheet helps learners apply the hundreds-place rounding rule consistently rather than copying the original number or rounding to a different place value. Its varied answer choices help teachers check whether students can distinguish an exact number from its rounded value and identify when the result moves to the next hundred. Designed for Grade 3 math practice, this free printable worksheet works for independent work, review, or a quick check of understanding. It includes a complete answer key so teachers can review responses efficiently.

FAQs

What does this worksheet cover?

This Grade 3 worksheet covers rounding two-, three-, and four-digit whole numbers to the nearest 100 through 10 multiple-choice questions. Students choose the closest hundred for values such as 125, 750, 963, 3,210, and 4,587, building accuracy with both numbers that stay within the same hundred and numbers that round up to the next one.

How can I use this worksheet to teach rounding to the nearest 100?

First model how to compare a number with the two neighboring hundreds, using a number line or the tens digit to decide which hundred is closer. Then have students complete the multiple-choice items and explain why a selected answer, such as 800 for 750 or 1,000 for 963, is closer than the alternatives.

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

Watch for students choosing a value rounded to the nearest 10, such as 120 or 370, instead of a multiple of 100. Students may also select 0 for 67, keep 750 unchanged, or miss the transition to the next hundred in items such as 963 and 4,587; ask them to compare the number with both neighboring hundreds.

How do I assign and grade this rounding worksheet?

This worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key for all 10 multiple-choice questions. Printable submissions can be graded by scanning student work with the Wayground for Teachers app, while the digital version supports online assignment and grading.

How can I differentiate this worksheet for my students?

For the 10 multiple-choice rounding items, use the worksheet’s Advanced Settings to adjust font spacing or increase the font size so the numbers and answer choices are easier to read. You can also apply a dyslexia-friendly font or translate the worksheet into another language when those options better support students working with the rounding tasks.
