Free decimal worksheets (grades 3-7)

This versatile generator produces worksheets for addition, subtraction, multiplication, and division of decimals for grades 3-7. You can create easy decimal problems to be solved with mental math, worksheets for multiplying by 10, 100, or 1000, decimal long division problems, missing number problems, and more. You can create the problems either in horizontal or vertical format (in columns).

You can vary the number of decimal digits, choose the font, font size, additional space under each problem, and more. Experiment with the options as you like, or choose from the ready-made worksheets list below.

When doing division, you can force the answers to terminate by ticking the box for "terminating division after max ___ more digits". Zero digits here will force division to terminate in the same number of decimal digits as what the dividend has.
