Start the week with a Spanish joke!
Jokes are a fun way to learn more about how a language works, as many of them rely on the subtleties of words and wordplay. This teaches students more about how to use the language, as well as hopefully raising a smile. Why not read a joke out in class and see who can translate it first?
Yo aprendí español con un CD rayado, así que solo puedo hablar español tartamudeando.
