Triple Digit Number Subtraction Regroup Worksheet

Subtracting three-digit numbers with regrouping is one of the biggest steps a second grader takes in math, and it is where careless place-value habits finally catch up with a student. This triple digit number subtraction regroup worksheet gives students focused practice trading one ten for ten ones and one hundred for ten tens, so the standard algorithm becomes something they genuinely understand instead of something they copy. Every problem on the page requires at least one regrouping, which means students cannot fall back on subtracting each column straight down without stopping to think about what the digits are worth.

This 2nd grade subtraction worksheet is ready to print and hand straight to a class. Students work through eight vertical subtraction problems, each set on a clean place-value grid so the ones, tens, and hundreds stay in perfect columns while they borrow. Two word problems follow, asking students to pull the numbers out of a real story — books on a school library shelf and cans collected for a class food drive — and write the difference on the line provided. Use it as morning work, as guided practice right after a mini-lesson, as a homework page, or as a quick check before a unit assessment.

What’s Included

• 1 print-ready PDF worksheet
• Answer key
• 8 vertical three-digit subtraction problems, every one requiring regrouping
• 2 real-world subtraction word problems with answer lines

There are three reasons this triple digit number subtraction regroup worksheet helps children learn the skill. First, the problems are arranged in true place-value columns, so students see exactly which digit they are borrowing from and never lose track of the tens place. Second, the mix of single-regrouping and double-regrouping problems keeps students checking each column instead of applying one memorized move to every question. Third, the two word problems move the skill out of the number sentence and into a situation a child recognizes, which is how state assessments will ask about it.

Teachers and parents can stretch this skill well beyond the page. Build the minuend with base-ten blocks and physically trade a ten-rod for ten unit cubes so children watch the regrouping happen. Have students explain one problem out loud to a partner using the words “trade,” “ten,” and “hundred.” Turn the answers into a scavenger hunt by taping the differences around the room. Give children real numbers to subtract — pages left in a chapter book, days until a holiday, or the difference between two team scores. Finally, ask students to invent their own three-digit story problem for a classmate to solve, then check it against a calculator together.
