This is a listening activity for the song Los 20 Ratones by Cantoalegre. This song (and many others!) can be downloaded here for free: http://www.musicalibre.com.co/Default.aspx?TabID=66&cid=11&Sid=778
In this activity students will listen to the song and complete it using the words from the word bank. There are also two short practice activities for diminutives and augmentatives in Spanish as the song uses these throughout.
