Mathematics
This Grade 3 mathematics worksheet helps students round three-digit numbers to the nearest hundred. It includes 10 questions: six fill-in-the-blank items that ask students to round numbers such as 314, 489, 655, and 867, plus four multiple-choice items that require students to identify which numbers round to, or do not round to, a given hundred. The worksheet builds practical understanding of how the tens digit determines whether a number rounds down or up to the nearest hundred. Students also practise recognizing groups of numbers with the same rounded value, including cases near hundred boundaries such as 999 rounding to 1,000. This free printable worksheet is designed for Grade 3 math practice, independent work, review, or a quick check for understanding, and it includes a complete answer key for efficient grading.

FAQs
What does this worksheet cover, and how does it help students learn to round to the nearest hundred?
This Grade 3 worksheet focuses on rounding three-digit numbers to the nearest hundred through six fill-in-the-blank questions and four multiple-choice questions. Students round individual numbers such as 314, 489, 655, and 867, then identify which numbers share a rounded value or do not belong in a group. This combination develops both procedural accuracy and the ability to recognize rounding patterns across several numbers.
How can I use this worksheet to teach rounding three-digit numbers to the nearest hundred?
First model one item by locating the hundreds and tens digits and explaining how the tens digit determines whether the number rounds down or up. Then have students solve the fill-in-the-blank examples before discussing the multiple-choice groups, such as numbers that round to 600 or numbers that do not round to 400. Ask students to justify one choice using a number line or the tens digit rather than selecting an answer by estimation alone.
What mistakes should I watch for when students complete this rounding worksheet?
Students may look at the ones digit instead of the tens digit, or they may change the hundreds digit in the wrong direction when the tens digit is 5 or greater. In the multiple-choice items, some students may focus on the target hundred and overlook the word “NOT,” while others may confuse the original number with its rounded result. Check boundary cases such as 489, 655, 867, and 999 to see whether students are applying the rule consistently.
How do I assign and grade this rounding worksheet?
You can assign this worksheet as a printable PDF or use it as a digital quiz on Wayground.
