2nd - 2nd Grade
Mathematics
This Grade 2 mathematics worksheet gives students focused practice finding 10 more, 10 less, 100 more, and 100 less than three-digit numbers. Across 20 questions, including 17 fill-in-the-blank items and 3 multiple-choice questions, students work with number sentences and short word problems involving changes of 10 or 100. Examples include adding 10 to 709, subtracting 100 from 399, and determining how many objects remain after losing 100. The worksheet helps students connect place-value changes to addition and subtraction without requiring them to calculate by ones. It is useful for introducing the effect of changing the tens or hundreds digit, reinforcing mental-math strategies, or checking whether students can apply the skill in simple contexts. This is a free printable worksheet with a complete answer key for Grade 2 math practice.

This Grade 2 worksheet practices finding 10 or 100 more and 10 or 100 less than three-digit numbers. Its 20 items use mostly fill-in-the-blank number sentences, with multiple-choice questions and short word problems that require students to apply the correct place-value change.
First model how adding or subtracting 10 changes the tens place and how adding or subtracting 100 changes the hundreds place, using examples such as 709 + 10 and 399 - 100. Then have students complete the fill-in-the-blank items and discuss how the word problems about dice, rocks, and flowers signal whether to add or subtract 10 or 100.
Watch for students confusing 10 with 100, changing the wrong place-value digit, or reversing more and less. In the word problems, students may choose addition when an amount is lost or subtract when more objects are added; the multiple-choice items can help reveal whether the error is computational or conceptual.
On Wayground, you can assign this worksheet as a printable PDF or as a digital quiz, and it includes a complete answer key for checking the 17 fill-in-the-blank and 3 multiple-choice questions. Printable submissions can also be graded by scanning student work with the Wayground for Teachers app.
