Trading cards and flash cards are a great way to teach children about the Catholic faith. There are flash cards in question-and-answer format that can be used in a classroom or at home. You'll also find flashcards that teach Catholic children about particular topics of the Catholic religion. In addition to their educational value, Children's trading cards are a fun way for Catholic children to exchange them in a trading card activity, and trading cards may also be used as a reward for a job well done in the classroom. Trading cards and flashcards are both excellent tools for supplementing other resources for teaching the Catholic faith.
