Three Digit Subtraction with Regrouping Base Ten Blocks is a Grade 2 mathematics worksheet that develops accurate subtraction of three-digit numbers when regrouping is needed. Students work through 20 items: 16 multiple-choice questions and 4 fill-in-the-blank questions. The tasks include finding differences such as 621 − 243 and 343 − 126, deciding whether regrouping is required, and recording answers using place-value reasoning supported by base-ten blocks. This free printable worksheet gives students structured practice connecting concrete base-ten representations to written subtraction procedures. It is useful for introducing regrouping, reinforcing a lesson, checking understanding, or providing independent practice. The included answer key helps teachers quickly review students’ calculations and identify whether errors come from recognizing the need to regroup or subtracting inaccurately across the hundreds, tens, and ones places.

This Grade 2 worksheet focuses on subtracting three-digit numbers with regrouping, using base-ten blocks to support place-value reasoning. Its 20 questions—16 multiple choice and 4 fill in the blank—ask students to find differences and decide whether regrouping is needed, helping them connect concrete models with written subtraction.
Begin by modeling one of the worksheet’s subtraction problems with hundreds, tens, and ones blocks, then demonstrate exchanging one hundred or ten when a place does not have enough units to subtract. Before students complete the multiple-choice and fill-in-the-blank items, ask them to explain whether regrouping is needed and which place-value unit must be exchanged.
Watch for students who select “no” when a subtraction problem requires an exchange, or who regroup from the wrong place-value column. Students may also subtract digits without accounting for the exchanged ten or hundred, producing an incorrect difference even when they identify that regrouping is needed.
This worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key for all 20 items. You can grade printable submissions by scanning student work with the Wayground for Teachers app, while the digital version can be assigned and scored online.
In the worksheet’s Advanced Settings, adjust font spacing or choose a larger font size to make the subtraction problems, answer choices, and fill-in-the-blank items easier to read. You can also select a dyslexia-friendly font or translate the worksheet into another language without changing its three-digit regrouping practice.
