Abstract
An educational game for teaching the fundamentals of dimensional analysis, including a chip imprinted with an equal sign, and at least one set of cards. Each set of cards includes at least three (3) cards, each card having first and second faces, each face imprinted with a line bisecting the face to form top and bottom generally rectangular halves. On each card a first symbol is imprinted on the top half of the first face and the same symbol is imprinted on the bottom half of the second face, while a different symbol is imprinted on the bottom half of the first face and that symbol is also imprinted on the top half of the second face. Each symbol appears on an even number of cards. To play the game, one card, denoted the target card, is placed on a surface to the right of the equal sign chip, while the remaining cards are arranged in random order in a row to the left of the equal sign chip, with random faces exposed and the corresponding second faces hidden, the bisecting line of all cards being generally colinear. The cards to the left of the equal sign chip are then, if necessary, flipped to expose the hidden faces until the symbol on the top half of each source card is matched by a symbol on the bottom half of another source card, except for one top half symbol and one bottom half symbol, which match the top half and bottom half symbols, respectively, of the target card.
