LatestSquare One Television is an American children's television program produced by the Children's Television Workshop to teach mathematics and abstract mathematical concepts to young viewers. Created and broadcast by PBS in the United States from January 26, 1987 to November 6, 1992, the show was intended to address the math crisis among American schoolchildren. After the last episode aired, the show went into reruns until May 6, 1994. The show was revived for the 1995–1996 PBS season as a teacher instruction program, Square One TV Math Talk. Square One was also shown on the U.S. cable television channel Noggin in syndication beginning in 1999, but was removed from its lineup along with other Sesame Workshop shows on May 26, 2003.
