Abstract: An apparatus for educating children includes a sock with an open end and a closed end. The apparatus includes a first sock symbol located on the first side of the sock which is oriented with a top of the first sock symbol oriented toward the closed end of the sock. The apparatus includes a second sock symbol located on the second side of the sock toward the closed end which is oriented with a bottom of the second sock symbol toward the closed end of the sock. Bending an end of the sock toward the first side inverts the second sock symbol and places it and a portion of the second side in a position to be viewed from the first side of the sock. The first and second sock symbols differ. The first and the second sock symbols are related to a same sock topic.

Abstract: An apparatus for educating children includes a first symbol for application to a first article of clothing and a second symbol for application to a second article of clothing. The first article of clothing is worn by a user at a same time as the second article of clothing and the first article of clothing and the second article of clothing are both part of a clothing set. The second symbol is non-identical to the first symbol and the first symbol corresponds to and matches the second symbol based on a relationship of an educational topic.

Abstract: An apparatus and method for matching socks or other substantially identical objects comprises a first sock with a first symbol disposed on it and a second sock with a second symbol disposed on it. The second symbol is non-identical to and associated with the first symbol. The symbols may be associated with each other by comprising a query and response, different representations of the same concept, two parts of a whole, source or origin, and other associations. The apparatus and method assist in matching as well as in teaching desired concepts.
