Teaching tips and what to try next

Use this with fourth graders who subtract three-digit numbers with regrouping, as in Three-Digit Subtraction With Regrouping, and can regroup across a zero as in Subtracting Across Zeros. Shading the column being worked on keeps a child's place on longer problems. Then mix both operations in Multi-Digit Addition and Subtraction, or review the standard at 4.NBT.B.4.

10 versions, each with its own answer key

Same skill and layout, a fresh set of problems in every version, so children can keep practicing without repeating a page. Problems are not repeated between versions unless a skill has only a small number of possible problems (for example, the addition facts within 10).

About this worksheet

Fourth graders are expected to subtract multi-digit numbers fluently with the standard algorithm. Four-digit problems build that fluency, because children have to regroup in more than one column and keep track of each change. This fourth-grade worksheet gives sixteen vertical subtraction problems.

The top number in each problem is between 2,000 and 9,999, and the bottom number is between 1,000 and the top number. Every problem needs regrouping in at least two columns, and some need it in three. Some problems have zeros in the top number, so children must regroup across a zero, which is where most mistakes happen. Each of the ten versions has new problems and its own answer key.

How to use it: remind your child to start with the ones column and move left. Before subtracting in a column, ask, "Is the top digit big enough?" If it is not, regroup one from the next place and cross out and rewrite the digits neatly above. A common mistake is subtracting the smaller digit from the bigger one in every column, no matter which is on top; regrouping fixes that. After each problem, check by adding the answer to the bottom number; the sum should match the top number. A quick estimate, rounding both numbers to the nearest thousand, also shows whether an answer makes sense.
