Transition Songs:
During my experience, I was able to see some of the techniques that the teachers use to keep the students under control. They used a lot of songs to help the students transition from one activity to the next. We have been talking a lot about this in class. Transition songs are fun little songs you can either have memorized or make up on the spot to direct the students' attention to you or the next activity.
One example is:
Clean up, clean up,
Everybody, everywhere!
Clean up, clean up,
Everybody do their share!
When you use these transitions, you need to also use other cues to help the students. Using body movements or changing your voice will have a better affect on the student. If you want the students to sit down for a read aloud, you will lower your voice while singing.
Here's another article I found with more examples of transitions:
