In everyday life, no matter where you are, communication is far more important than eloquence. Have you ever forgotten the name of an object and said, "You know, the uhh... thing with the wheels." Most normal people would guess that you meant a car.
Magnetic poetry becomes a really useful tool because, like a regular ESL learner, you are limited in your vocabulary -- and like a forgetful old man like me, sometimes you have to be creative in your descriptions in order to convey your message.
This activity serves as an excellent vocabulary, sentence building, and creative tool in any classroom. Feel free to play below -- but don't get too addicted!
