One of the greatest challenges for teachers is smooth transitions between activities.  We often loose control of the class to chatter and chaos when we ask them to move from one location to another.  In the SMART Notebook gallery, you will find a variety of dice.  Choose one that can be edited.  I prefer to label the six sides with table 1, table 2, table 3, etc.  A student helper taps the die, and the next group to line up is decided.  The students remain quiet as they anticipate the next roll.  Movement is done in small chunks and so much time and energy is saved!  Give it a roll in your classroom.  You’ll just “die” for these smooth transitions!
