Printable Adding 1 Flash Cards
Adding 1 is the first fact family in arithmetic: one more. Every card answers with the next number in the count — 7 + 1 is simply the number after 7. These fold-over flashcards cover 1 + 1 through 12 + 1.
How to Use These Flash Cards
Say the count out loud: for 8 + 1, the answer is one step along, so a child who can count already knows it. This deck builds confidence — run it fast and use it as the warm-up before the harder families. If a card stalls, count up from the first number with fingers once, then flip.
How to Cut and Fold
- Print the PDF single-sided on plain paper or light cardstock.
- Cut along the solid lines to separate the cards.
- Fold each card along the dashed center line so the answer sits behind the question, and turn the card over like a page to check.
- Optional: a dab of glue inside the fold makes a sturdy double-thick card.
Frequently Asked Questions
Why drill adding 1 if it is just counting?
Because the goal is recognizing that it IS counting. Children who connect +1 to "the next number" stop computing it — and that insight is the doorway to counting on, the strategy behind +2 and +3.
What age is the adding 1 deck for?
Kindergarten and early 1st grade, as soon as counting to 13 is comfortable. It is usually the first flashcard deck a child can run clean.
What should come after the +1 facts?
The +2 facts, which extend the same counting-on idea two steps, and then doubles (2 + 2, 3 + 3...) which anchor the harder families later.
