These flashcards can be printed out on cardstock or regular paper. Print on both sides so the answers are printed don the back of each card.
After printing, cut along the dotted line. I use the black circle as a guide to show students where to start and then instruct them to cut around the border instead of cutting each card individually (this makes cleanup a lot easier).
They can be used for a math center, homework practice, or just to practice doubles math facts.
