lisa,
Questions, discussions, and active ingagement (writing ideas on flip charts, white board, leading a discussion) are examples of ways to reingage distracted students. Sometimes, just simple tasks can reinvigorate students, such as circulating about the room, teach for 10-minutes, ask questions for 5-minutes. This last suggestion puts students on notice they're likely to be called on and therefore, need to pay attention in order to respond appropriately.
