About this worksheet
3-digit adding and subtracting problems in big hundreds, tens and ones boxes. Regroup boxes show up only on problems that need them. Fewer and More change how many. Includes an answer key.
What kids practice
In 3rd grade, kids write more: whole paragraphs, longer answers and 3-digit math. For kids who find handwriting slow, tiring or messy, including kids with dysgraphia, that can turn every assignment into a fight. These sheets lighten the load. Models are traced right above the writing line, sentence starters cut down how much kids write, colored chunks and boxes keep their place, and hand breaks are built in. They are not a test or a diagnosis. If writing is still much harder for your child than for other kids, talk with their teacher or ask about an evaluation with an occupational therapist.
Watch for
- Gripping the pencil too tightly. Shake out the hand and try a lighter pinch.
- Copying from far away, like the board. Keep the model right above the writing line.
- Long writing jobs with no breaks. Use the hand breaks on the stamina ladder.
- Numbers drifting out of their columns in math. Use the place-value boxes.
- Judging ideas by how neat they look. A messy page can still hold great thinking.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full handwriting helpers (dysgraphia-friendly) guide for 3rd grade.
