Peer pressure role-playing activities can take the form of group skits. Divide your class into groups of four or five. Have each group brainstorm and choose an idea for a situation involving peer pressure. For example, the situation can involve a student being pressured into skipping school by her friends. Have the groups write a skit with three different endings, comprising three possible tactics for resisting peer pressure. After groups perform their skits, have the rest of the class vote on the most effective strategy depicted in the endings.
One way to get students to role play on peer pressure is through improvisational games. Write down a number of scenarios involving peer pressure and place them in a hat. Come up with them yourself or solicit ideas from students. Have two students come to the front of the room, choose a scenario at random and improvise the situation. Yell "freeze" after the problem has been acted out. Ask the rest of the class for suggestions on how the situation could be resolved productively. Have the two students improvise different suggested endings. Allow lighthearted ones in addition to serious ones. Repeat the exercise with different volunteers.
Another useful role-playing activity involves having students see what it's like to play opposite roles in a peer pressure situation. Give each pair of students a different peer pressure scenario to act out. Alternatively, you can allow groups to come up with their own scenarios. Have students work up two versions of the same skit, giving each student a chance to play both the "bully" and the student being pressured. Have students perform their two versions and discuss how they differed.
Arts and crafts can help with role-play, especially for younger students. Have students decorate a paper lunch bag with googly eyes, markers and anything else. Teach young students what peer pressure is and how it can be overcome. Working in groups of two or three, let students use their paper-bag puppets to come up with skits about peer pressure. Alternatively, read a story aloud about peer pressure and have students act out tense situations with their puppets as you read.
