2nd - 2nd Grade

Plus 1, +1, 1 More Than is a Grade 2 math worksheet focused on adding 1 to numbers from 10 through 19. Its 20 multiple-choice questions ask students to solve equations such as 11 + 1, 1 + 14, and 19 + 1, helping them identify the number that comes immediately after a given number and recognize that reversing the addends does not change the sum. This free printable worksheet is useful for introducing, reinforcing, or checking students’ fluency with one-more addition within 20. Students select an answer from several choices, so the format also gives teachers a quick way to spot counting errors, reversed operations, and distractor-based misconceptions. The worksheet includes a complete answer key for efficient review and grading.

FAQs

What does the Plus 1, +1, 1 More Than worksheet cover?

This Grade 2 math worksheet develops the skill of adding 1 to numbers from 10 through 19. Across 20 multiple-choice questions, students solve equations such as 13 + 1 and 1 + 17, then choose the next number in the sequence, building accuracy with one-more addition within 20.

How can I use this worksheet to teach adding 1?

First model how adding 1 means counting forward one number, using an equation such as 14 + 1 = 15. Then have students solve a few examples with a number line or counters before completing the multiple-choice items independently. Ask students to explain why both 1 + 14 and 14 + 1 have the same sum when reviewing their answers.

What mistakes should I watch for on this adding-one worksheet?

Watch for students choosing the original number instead of the number one greater, such as selecting 13 for 13 + 1. Some may subtract 1, confuse the addends, or combine the digits incorrectly, as suggested by distractors such as 112 or 117. Review each error by having the student count forward exactly one step from the given number.

How do I assign and grade this Plus 1 worksheet?

Wayground provides this worksheet as both a printable PDF and a digital quiz, so you can assign the 20 multiple-choice questions in the format that fits your lesson. It includes a complete answer key for checking student responses, and printable submissions can be graded by scanning student work with the Wayground for Teachers app. The PDF option can also support schools that are reducing screen time.

How can I differentiate this adding-one worksheet for my students?

Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the multiple-choice equations and answer choices are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language when those options support access to the adding-one practice.
