Adding Single/Double Digit Numbers is a Grade 2 mathematics worksheet that gives students repeated practice solving addition equations with single-digit addends and simple sums involving a two-digit number, such as 50 + 9. Students answer 18 multiple-choice questions and complete 2 fill-in-the-blank items, selecting or writing the sum for each expression. This free printable worksheet helps students build addition fluency, connect equations with numerical answers, and check their understanding across sums with different-sized addends. The varied answer choices provide practice distinguishing accurate sums from closely related distractors, while the fill-in-the-blank items require students to produce an answer independently. It is useful for independent practice, a short skills check, homework, or review after introducing single- and double-digit addition. A complete answer key is included for efficient checking and feedback.

FAQs

What does the Adding Single/Double Digit Numbers worksheet cover?

This Grade 2 worksheet practices finding sums for addition equations with single-digit addends and simple expressions that include a two-digit number, such as 50 + 9. It contains 18 multiple-choice items and 2 fill-in-the-blank items, helping students build fluency while practicing both selecting and independently writing the correct answer.

How can I use this worksheet to teach adding single- and double-digit numbers?

First model how to read each addition expression and combine the quantities, then solve a few of the worksheet’s single-digit examples together. Use the multiple-choice options to ask students how they can rule out incorrect sums, and have them explain how they solve the two-digit example before completing the fill-in-the-blank items independently.

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

Students may choose a distractor that reflects counting one too many or one too few, especially in sums such as 7 + 6 or 5 + 8. Watch for students who do not preserve the tens and ones when solving an expression such as 50 + 9, and check that they write a complete numerical answer in the fill-in-the-blank items rather than copying an option.

How do I assign and grade this adding numbers worksheet?

The worksheet is available as a printable PDF and as a digital quiz on Wayground, so you can assign the format that fits your Grade 2 math lesson. It includes a complete answer key, and printable submissions can be graded by scanning student work with the Wayground for Teachers app. The printable version can also support classrooms that are reducing screen time.

How can I differentiate this addition worksheet for my students?

Use the worksheet’s Advanced Settings to adjust font spacing or increase the font size so students can more easily scan each addition expression and its answer choices. You can also select a dyslexia-friendly font or translate the worksheet into another language when that will make the directions and fill-in-the-blank items more accessible.
