This is a twist on the classic flyswatter game (teacher gives a prompt and students try to hit the prompt with a flyswatter before all other students).
You will need: 4-6 groups in your class, one flyswatter per group, and one whiteboard/dry erase marker/eraser per group.
Call up 1 representative from each group for the flyswatter portion. You say something like "I sing." Whoever swats "canto" first gets 1 point for their team. All reps go back to their tables.
Here's the TWIST.
Each group has 1-2 minutes to brainstorm a sentence with "canto" in it and write it on their white board. For example, "Yo canto con amigos en la clase de mu'sica." When you ring a bell, all groups hold up their sentences. Any group that has a correct, detailed sentences gets 2 points.
Call up a new rep from each group for the next flyswatter attempt.
