Add Subtract Multiples of 10 and 100 is a Grade 4 mathematics worksheet that develops fluency with place-value changes and related addition and subtraction strategies. Across 20 items, students identify multiples of 10, round numbers to the nearest ten before adding, find numbers that are 10 or 100 more, and solve addition and subtraction equations. The worksheet uses four fill-in-the-blank questions, 11 multiple-choice questions, three drag-and-drop items, and two dropdown questions. Students also connect subtraction with finding the difference between two numbers, including examples such as subtracting 10, adding 30, and solving a two-digit subtraction problem. This free printable worksheet includes a complete answer key and is suitable for guided practice, independent review, or a quick Grade 4 skills check.

This Grade 4 worksheet practices identifying multiples of 10, rounding two-digit numbers to the nearest ten and then adding, finding 10 or 100 more than a number, and solving addition and subtraction equations. Its 20 items use fill-in-the-blank, multiple-choice, drag-and-drop, and dropdown formats, requiring students to apply place-value patterns and recognize subtraction as finding a difference.
First model how a digit changes when 10 or 100 is added or subtracted, then have students explain examples such as 254 becoming 354 when 100 is added. Next, demonstrate rounding each addend to the nearest ten before solving problems such as 13 + 78, and use the worksheet’s varied response formats for guided practice before assigning the remaining items independently.
Watch for students adding 10 instead of 100 in items that ask for one hundred more, or choosing an answer that changes the wrong place-value digit. Students may also add the original numbers instead of rounding first, round 46 in the wrong direction, or choose addition when asked to find the difference. The drag-and-drop and dropdown items can reveal whether students understand the relationship rather than selecting an answer by guesswork.
The worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key for checking all 20 items. Printable submissions can be graded by scanning student work with the Wayground for Teachers app, while the digital quiz can be assigned for online response collection and grading.
Use the worksheet’s Advanced Settings to adjust font spacing and font size so the equations, answer choices, and interactive-style prompts are easier to read.
