This one or two day activity for absolute beginners practices pronouns and forms of ser while building automaticity and confidence in the language.
I use this activity with absolute beginners in grades 5-7, though it would work well with older beginners, as well. Students are already familiar with the question ¿De dónde eres? and the response “Soy de __.” Each of them is assigned a Spanish-speaking city, and they must interview their classmates to find out where everyone is from. Afterwards, there is data compilation in Spanish and a brief discussion that requires students to use different forms of ser.
If your class includes geography of the Spanish-speaking world, you could spend extra time having students group themselves by continent/region/climate zone.
