On-Sets

= On-Sets =  This game is very valuable in teaching about spatial relationships. The mathematical content of the game is Set Theory. Players learn to create and describe sets of colored objects using Union, Intersection, Set Difference, Set Complement, the Universe, and the Null Set. The practical applications of this game are relevant to use of the internet. In researching a specific article on the internet, a person finds the best articles by using a search engine and including information needed and restricting information that is not needed. This concept of narrowing down information to get exactly what one wants is highly developed in the game of On-sets.

Each division level of competition introduces increasingly more difficult mathematical concepts for the players to use by adding age appropriate variations to the basic game. Players are challenged to use their mathematical knowledge and skills in increasingly creative ways and usually learn more from applying their knowledge in the competition than they do in their normal classroom studies.
