Abstract: A game comprising a ball field and playing apparatus, the ball field comprising a substantially flat surface having three playing zones, lines delineating a starting point for a pair of offensive team runners, first and second circles disposed in the first zone for defensive team members, base pads disposed in the first zone, lines delineating first and second safety lanes, respectively, the first and second bases being at the juncture of the first and second zones, a third circle disposed in the center of the surface, third and fourth base pads disposed on the juncture of the second and third zones, third and fourth bases disposed respectively at the inward ends of the third and fourth safety lanes and in the third zone, and a delineation of "home" and the playing apparatus comprising a flexible pole upstanding from the center of the third circle, a game ball, the pole being at its free end adapted to releasably retain the ball thereon, and barrier means disposed between the third and fourth bases and the de

Abstract: An apparatus for educational use in the playing of mathematical games utilizes forty-four playing cards. Each of the cards bears an enlarged numeral extending over the ranges from one to forty-four. Each card has the same surface carrying the enlarged numeral encoated wtih three multiplication steps and three division steps whereby one common numeral is used in each multiplication step and as a divisor in each division step. None of the numerals is extended beyond number 12 excepting the enlarged identifying numeral. The users record their proficiency in rapid use of each card, when randomly collected, on a score board having four wheels with a score imprinted thereon. The wheels are rotatably secured to a plate having windows exposing the score value on the wheels. Each of the four wheels are separately identified by a color, equivalent to the color of each four separately decorated medallions.
