  1. El Barquito

This song is a nice little tongue twister but easy enough for young kids to accomplish with some practice.  If you teach it to them slow and start to increase the tempo the will catch on quickly.  It's a fun tune to perform and many older people know it from their childhood. 

Lyrics

V1.  Habi­a una vez un barco chiquito 3x
       Tan chiquito, tan chiquito, no podia navegar.
V2.  Pasaron una, dos, tres, cuatro, cinco, seis, siete semanas 3x
       Y el barquito, tan chiquito, no podi­a navegar. 
V3.  Y si la historia no les parece larga 3x 
       Volveremos, volveremos, volveremos a empezar.
