This Grade 3 mathematics worksheet gives students focused practice rounding whole numbers to the nearest 10 and nearest 100. It includes 10 fill-in-the-blank questions, with items such as rounding 62 to 60, 97 to 100, 434 to 400, and 681 to 700. Students must identify the place value being rounded and use the next digit to determine the correct multiple of 10 or 100. Use this free printable worksheet for independent practice, a quick formative assessment, math-center work, or review after introducing rounding strategies. The mix of two-digit and three-digit numbers helps students distinguish between rounding to the nearest ten and rounding to the nearest hundred. A complete answer key is included so teachers can check student understanding efficiently and address errors in place-value reasoning.

WorksheetsAnswer KeyThis Grade 3 worksheet covers rounding two- and three-digit whole numbers to the nearest 10 and nearest 100 through 10 fill-in-the-blank questions. Students identify the target place value, examine the digit to its right, and write the appropriate multiple of 10 or 100, such as 756 rounding to 800.
First model one nearest-ten example and one nearest-hundred example, clearly naming the place being rounded and the next digit used to make the decision. Then have students complete the fill-in-the-blank items, asking them to explain why answers such as 45 becomes 50 while 434 becomes 400. Review the completed worksheet by sorting errors into incorrect target place value and incorrect rounding decision.
Students may round to the wrong place, such as treating a nearest-hundred question like a nearest-ten question, or write a number that is not a multiple of the requested place value. They may also inspect the wrong digit—for example, missing that 198 rounds to 200 and 681 rounds to 700. Check that each fill-in answer matches the stated place: tens for questions such as 62 and 87, and hundreds for numbers such as 756 and 777.
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 fill-in-the-blank questions. You can grade printable submissions by scanning student work with the Wayground for Teachers app, or review responses from the digital quiz.
Use the worksheet’s Advanced Settings to adjust font spacing or increase the font size so the fill-in-the-blank prompts and answer spaces are easier to follow. You can also apply a dyslexia-friendly font or translate the rounding questions into another language when that better supports students’ access to the worksheet.
