Want to add a sense of urgency to your rehearsal or class? Online-stopwatch is your answer! This free tool allows you to set a countdown timer to minutes or hours. This was a great way to keep the students on-task and focused as they worked with a partner on their Lewis & Clark wiki's. The students were more productive knowing exactly how much time was left in class.
