What is "numbertime"

Numbertime is a BBC educational television series for primary schools that was aired on BBC Two from 20 September 1993 to 3 December 2001. For its first four series, it was presented by Lolita Chakrabarti. El Nombre, an animated character from Numbertime, eventually became the concept for another educational BBC children's television program; his name means "The Name" in Spanish, and not "The Number", which would be "El Número". The third line of his opening song and his farewell catchphrase were also changed several times during the series' run, to reflect their focus - however, the original ones ("Writing numbers in the desert sand" which was also used for the seventh series, and "Adios amigos, and keep counting" which was also used for the fourth, sixth, seventh, eighth and ninth series) remain the most famous.

For the second series, El Nombre's tagline and farewell catchphrase were changed to "Drawing shapes in the desert sand" and "Adios amigos, and keep shaping up" respectively, while for the third series, they were changed to "Righting wrongs in the desert sand" and "Adios amigos, over and out" respectively; however, for the fourth series, his tagline was changed to "Counting numbers in the desert sand" (which was also used for the ninth series), and for the third episode of the fourth series, his farewell catchphrase was changed to "Adios amigos, and fetch some water". For the fifth series, both his tagline and farewell catchphrase were changed to "Telling time in the desert sand" and "Adios amigos, 'till the next time" respectively, while for the sixth series, his tagline was changed to "Using numbers in the desert sand"; finally, for the eighth series, his tagline was changed to "Counting money in the desert sand".
