There is shown card game apparatus and method of play for use in educating children in basic mathematical concepts, the apparatus including a six-sided mathematical function indicator, such as a die, used in combination with two sets of cards, the function generator containing notation on a side indicating a different arithmetic operation such as addition, subtraction, multiplication and division, and on a fifth and sixth side game playing instructions. The first set of cards, some dealt to the players, include selected sets of cards each set numbered 1-10. The second set of cards consists of ten cards numbered 1-10 that are stacked to provide unit numbers used in the mathematical process indicated by the function indicator. In playing the game a player determines a problem to be solved by combining a card from the first and second sets and the mathematical function to be utilized, and then uses cards from his hand to demonstrate solution of the problem, the object of the game to rid ones hand of all cards.
