With these cards your students can practice addition, subtraction, halving, doubling and multiplication! You can make your own flashcards or let the students play matching games. Great resource for math centers! Enjoy.
P.S: Don't print them double sided because I'm not sure if they'll match up. I printed them out and then my students played match-up and made the cards.
