3-Digit Number Line Addition is a free printable Grade 2 mathematics worksheet that helps students add three-digit numbers within 1,000. The 19 multiple-choice questions include equation-based sums and short word problems, giving learners practice combining ones, tens, and hundreds and recognizing when regrouping is needed. Problems include varied values such as 509 + 134, 516 + 468, and real-world totals involving marbles or time spent outdoors. This worksheet is useful for guided practice, independent classwork, homework, or a quick check of addition fluency. Students must calculate each sum accurately and select the matching answer from plausible choices, which can reveal errors in place-value alignment, regrouping, or interpreting a word problem. A complete answer key is included, and the worksheet is available as a free printable resource for Grade 2 classrooms.

WorksheetsAnswer KeyThis Grade 2 worksheet covers adding three-digit numbers, including sums that require attention to ones, tens, and hundreds and may involve regrouping. Its 19 multiple-choice items combine direct equations, such as 509 + 134 and 516 + 468, with word problems that ask students to find a total, so learners practise both computation and applying addition to a situation.
Begin by modeling one equation in expanded or place-value form, showing how the ones, tens, and hundreds are combined before students work through the multiple-choice items. Ask students to explain why an answer choice is reasonable and to identify where regrouping occurs in problems such as 698 + 133 or 516 + 468. Then use the marble and time word problems to connect the same addition process to finding a total in context.
Watch for students who add digits without preserving place value, especially when a ones or tens sum requires regrouping. The answer choices also make it possible to spot skipped regrouping, incorrect digit alignment, or selecting a result that reflects only part of the calculation. In the word problems, check that students add both quantities and answer the question about the combined total rather than using just one number.
You can assign this worksheet as a printable PDF or as a digital quiz on Wayground, and it includes a complete answer key for all 19 multiple-choice questions. For printable submissions, scan student work with the Wayground for Teachers app to help grade responses. The printable format also offers an option for schools that want to reduce screen time.
Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the three-digit equations and answer choices are easier to read. You can also apply a dyslexia-friendly font or translate the worksheet into another language when that supports access to the addition problems and word-problem text.
