Trio is played like Go Fish, but with guided conversations using your vocabulary and grammar. The sample included uses adjectives to describe personalities, for example, "Is Susy generous or stingy?" Students can help to come up with questions to be used in the game, as well as possible answers. Then they can help illustrate the cards. These steps take time, but can be integrated into your lesson.
My students and I brainstorm appropriate questions and answers at the beginning of the lesson; I print and copy the card templates and give a full sheet (9 cards per sheet) to each student. The students write in an answer (in pencil!) to the question, and then they peer edit their cards. Then each student illustrates the set of 9 cards to reflect the answer chosen.

At the end of the lesson students turn in their illustrated cards, we put groups of them together to form decks, and then play Trio!
