Reply:A double sided card; one side with the question, the other with the answer.
Reply:Question is on side of the card and the answer is usually on the other side of the card.
Reply:usually index cards with a word or question that needs to be studied on one side and the answer on the other. it help memorize things
Reply:Think of them as your little helpers. They guide you through life and give you very good opertunities. (It builds character)
Reply:You get a package on 3 x 5 index cards. On one side of the card you write the question, on the other side, the answer. You keep going through the cards, and the ones you find you can answer easily, you remove from the stack, spending more and more time on the questions you are having trouble with. You can use them for other things beside Q and A. I used them in Biology for identifying animal genus and species. The point is that you can reinforce your learning by studying both sides of the cards. For example, if you go through and know all answers, try reading the answers and see if you know the questions. It's the best way to learn things that require rote memorization.
