These are the lyrics of Patti Lozano's Jugo de naranja song with the gustar verbs deleted. Some of the indirect object pronouns are left in. ("me" is the only on in the song). Give the students this after you've introduced the topic, let them try it as you walk around, then play the song as they check it. The link is on the paper.
This paper has two songs per sheet, but is easily editable.
Clearly review when to use "gusta" v. "gustan" before giving this paper. It is a great tool to train students to look at the word after gustar ONLY for singular v. plural conjugation in gustar.
5-10 minute activity, depending on the size of your class. It works well for bellwork or a transitional activity.
