156 printable subtraction fact flashcards for grades 1–3, covering the facts from 0 to 12. Fold-over cards with the difference on the back, grouped by fact family — −1 through −12, plus a zero-facts family.
What students practice
Students build fluency with the subtraction facts and learn to think of subtraction as the inverse of addition — the reference page is an addition table for exactly that reason.
How the fold-over cards work
Every card prints as one piece: the problem on the front and the answer on the back. Cut on the solid border, fold along the dashed line, and the answer is already right side up — no double-sided printing and no lining up the backs.
