Square 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.

This emmy award winner for Best Animated Special is based on the first tale of C.S. Lewis' acclaimed children's books, "The Chronicles of Narnia." When four children pass through a special wardrobe closet, they discover the kingdom of Narnia, a land of talking animals and mythical creatures. But an evil witch's spell has cast Narnia into eternal winter. Fearing that an ancient prophecy has come true, and that the children are Narnia's chosen rulers, the witch tricks their youngest brother into betraying his family. Now, only Aslan, noble lion and King of the Woods, can help them defeat the witch, restore springtime to Narnia... and claim their rightful places on the throne.
