"Square One" comprised short sketches that introduced and applied concepts in mathematics such as counting, combinatorics, simple fractions, estimation, probability, and geometry. The sketches featured regular characters and were mainly parodies of pop culture icons, popular television commercials or popular television shows. Sketches were presented in various formats, including music videos featuring a particular subject in mathematics and taught the subject through song (e.g., Roman numerals, obtuse and acute angles, percentages, negative numbers, etc.) or comedic sketches (e.g., "General Mathpital", a parody of "General Hospital"; "Nobody's Inn", a parody of "Fawlty Towers"; "Late Afternoon with David Numberman", a parody of "Late Night with David Letterman"; etc.). "Patterns", a polka about patterns that can be detected in daily life, was performed by "Weird Al" Yankovic. Since Yankovic did not write this song, it is unavailable on any of his records, though bootleg versions have circulated. The Judds appeared on "Square One Television" many times, as they performed various songs.
