Subtraction Flashcards (0–20)
Subtraction facts within 20, shuffled and ready to cut out.
How to print: print the front pages first. For double-sided cards, load the same pages back into the printer and print the answer pages — the columns are already mirrored so each answer lands behind its question. Cut along the dotted lines.

About these flashcards
Subtraction facts are the inverses of the addition facts. Practise them together: if a child knows 8 + 7 = 15, then 15 − 7 = 8 should follow quickly.
Ways to use them
- Shuffle and go through them for two minutes a day; put the ones answered correctly in one pile and the rest in another, and revisit the second pile first next time.
- Play a quick game in pairs: each player turns over a card and the first to answer correctly keeps it.
- Print on card stock for durability, or laminate them for years of use at home or in class.
