This Grade 2 mathematics worksheet gives students focused practice finding 1 more, 1 less, 10 more, 10 less, 100 more, and 100 less than a given number. Across 15 multiple-choice questions, students work with one-, two-, and three-digit numbers, including items such as finding 100 more than 563, 1 less than 119, and 10 less in a short candy-store word problem. The worksheet helps students connect changes in a number to its ones, tens, and hundreds places while distinguishing between increasing and decreasing by different amounts. The multiple-choice format provides quick practice and makes it easy to identify whether students are confusing operations or place values. It is designed for Grade 2 math instruction, independent practice, review, or a short formative assessment. This free printable worksheet includes a complete answer key for efficient checking.

This worksheet covers finding 1 more, 1 less, 10 more, 10 less, 100 more, and 100 less than given numbers. Its 15 multiple-choice items, including a short word problem, help Grade 2 students determine how changing a specific place-value amount changes the number.
Introduce the worksheet by modeling how adding or subtracting 1, 10, or 100 changes the ones, tens, or hundreds place. Then have students explain why answers such as 51 for 10 more than 41 or 370 for 100 less than 470 are correct before completing the multiple-choice items independently. Use the final candy-store problem to discuss applying the same 10-less relationship in context.
Watch for students who add when the question asks for less, subtract when it asks for more, or change the wrong place-value digit. Students may also confuse 1, 10, and 100, such as treating 100 less than 674 as 574 or interpreting 1 less than 119 as 99. Ask students to identify the amount and direction before choosing an option.
Wayground provides this worksheet as a printable PDF and as a digital quiz, and it includes a complete answer key. You can grade printable submissions by scanning student work with the Wayground for Teachers app, or review responses from the digital version.
Most items provide direct number practice, while the final candy-store question asks students to use “10 less” to determine how many treats Cam received. This contrast helps teachers check whether students can transfer the same numerical relationship from a calculation item to a simple word problem.
