Free Timed Math Fact Worksheets (Mad-Minute Style)
Generate classic one-minute math drills for addition, subtraction, multiplication, and division. Choose the grid size (up to 72 problems per page), set the number range from single-digit facts to 2-digit problems, and print with an automatic answer key on page two. Subtraction never goes negative and division always comes out even — every sheet is solvable by design.
Unlike fixed worksheets, every problem here is editable: reroll any single problem you don’t like, lock the ones you want to keep, or type exact problems your class is working on. The same sheet can be regenerated endlessly — same skills, fresh numbers — so fact practice never repeats.
How teachers use it
Print a fresh drill every morning, run it as a one-minute timed challenge, and have students record their score in the box at the bottom. The five quick-start presets match the most common classroom formats: 1-minute addition and subtraction for grades 1–2, multiplication facts to 12 for grade 3, division facts, and 2-digit addition for building stamina.
