This is popular with students and successful in getting people interested in a unit on Mexico. I used it for several years in class before a Mexico Unit. I asked students to work in groups of 4 or so and to put their heads together to come up with their best answers to these questions. Giving some reward or recognition to the group that has the most correct answers really (really) appeals to every class I have seen. The answers are provided on the last page--you may not want to print them.
The inspiration for this activity was a Food Network magazine piece called "Test your Knowledge" about Chocolate. The magazine does it now for other food groups. It is almost irresistible once you start.
This is also a fine introduction activity (for perking interest) before a research project.
You do not need Spanish Language to complete this.
If you are doing the activity in the Spanish Language Classroom and having the teacher reveal the answers when groups are finished working, then... Do have in mind and show & write down on board for students the basic pieces of Spanish Language you will use to communicate ....like Right! (Acertado! Correcto Exacto...) something concrete... and likewise for wrong answers....
(Se han equivocado, lo siento.... )whatever you would usually say. You can have students write 5 sentences for practice as a concluding activity. Even a brand new Spanish student can learn "Aprendí que..." and then list a fun fact about Mexico. Pick the language pieces and stick to them so that after 20 answers revealed, those pieces of language have meaning for students.
