Flash cards are learning tools designed to help kids develop a deeper understanding of the world around them.  Information is printed on both sides of the card.  On one side, the learning concept is shown.  On the other side, the answer or solution to the concept is revealed.  For example, one side of a card may show a number and the opposite side of the card may have a visual representation of that number.  If a card has the number 5 on one side, it may have a dice showing five dots on the opposite side.
