 Presentation 1. Start with a natural dialogue that contains no more than twelve slang words and idioms 2. Based on the context of each phrase, allow the students to guess what each slang term or idiom means.!" 3. To really lock in the meaning, go around the classroom and have each student use the idiom "Real Speak" Practice the idioms in a dialogue with reductions. Provide a variety of reinforcement activities in pairs. A Sample Group Activity  Divide the class into two teams.  The teacher posts 36 cards in six rows of six. The cards are all clearly numbered 1 through 36. Half of the cards have slang words or idioms written on the back while the other half have the meanings.  The goal is to match a slang word or idiom with its meaning. With only one student choosing at a time, the teams take turns trying to choose two cards that match. When a match is made, the person who made the correct match must use that term in a complete sentence.
