Senteo interactive response systems or "clickers" allow your students to all participate at the same time. As a teacher, you can ask simple yes/no questions or multiple choice questions and view the results by individual students or as an entire class. Instant assessment information at your finger tips during the lesson. Best of all the Senteo system works with the SMART Board or with your LCD projector. Perry CSD currently owns 1 Senteo system and another one is on its way.
