Laid out in a T-H-T-O column format, this subtracting four-digit numbers worksheet opens with a worked reminder box showing how to line up digits by place value before subtracting ones, tens, hundreds, and thousands in order. Six numbered problems follow in large, easy-to-read vertical format, each with space below for students to show their work. The mix of problems includes numbers requiring regrouping, making it well suited for grades 3 to 4 in a homeschool math curriculum.

A bonus challenge problem at the bottom gives your student one extra problem to tackle independently once the main set is complete. The worksheet works well as a guided lesson introduction when you walk through the reminder box together, or as independent practice once your homeschooler is comfortable with the column subtraction process. Completing it builds the habit of aligning place values before computing, a foundational step for multi-digit arithmetic.
