For a fun way to allow multiple students to respond at the same time, try making speech bubbles out of poster board. Laminate them, glue or tape them to paint stirrers, and provide students with dry erase markers and erasers or old socks. They'll have a blast, and you'll increase the level of student engagement in your classroom.
