Ten vertical addition problems fill this adding four-digit numbers worksheet, each one pairing two four-digit addends with generous work space below for carrying and showing steps. A tip box at the top reminds students to line up digits by place value and begin adding from the ones column, and a fully worked example walks through 2378 plus 1465 before your student tackles the ten problems on their own. This sheet sits comfortably in a grades 3-4 curriculum, particularly when your student is moving from three-digit to four-digit sums.

The layout supports independent practice once your homeschooler understands regrouping, but it also works well as a guided first pass if four-digit addition is still new territory. Completing all ten problems builds the habit of working right to left across place values, reinforces carrying into the thousands column, and gives you a quick snapshot of where regrouping breaks down. Drop it into a math unit study or use it as a warm-up on computation days.
