156 printable addition fact flashcards for grades 1–3, covering the facts from 0 to 12. Fold-over cards with the sum on the back, grouped by fact family — +1 through +12, plus a zero-facts family.

What students practice
Students build automatic recall of the addition facts, the foundation every later strategy — regrouping, mental math, and multi-digit addition — is built on.
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.
