4-Digit Addition Worksheets
Large-number addition with carrying across thousands. Click New worksheet for a fresh sheet, then print it with its answer key.
About this worksheet
Addition practice sheets that never repeat: choose the size of the numbers, whether problems need regrouping (carrying), and whether they are stacked or written in a line. Every sheet comes with an answer key, so parents and teachers can check work in seconds.
Tips for parents and teachers
- Start with sums within 10 using fingers or objects, then move to written problems.
- For regrouping, have children add the ones column first and write the carried 1 above the tens.
- Short daily practice (one sheet) works better than a long weekly session.
