Kindergarten

Yesterday I helped in a Kindergarten classroom in the morning.  I will be working with one of the students throughout the the summer, and the teacher and I are working together now to get things ready for summer.  During my 3 hours in the classroom, I was able to see a few things I would love to do in my classroom.  She incorporated technology, movement activities, and discussions into her lessons keeping her students involved in lessons.  She used "feed the pig" as a behavioral tool, having student pay one of their coins when they were not following directions.  What have you used or seen used in classrooms?
Throughout the class, the students were using the interactive whiteboard, and were able to take turns doing each activity.  Personally my favorite activity was when the class completed the song "When You Subtract with a Pirate".  The students were singing along and answering the math problems.  It turned a lesson into a fun activity. What activities have you seen used to teach rather than just lecturing?
Students and teachers also provide positive support for each other, giving positive comments throughout the day.  These are called bucket fillers, and they write them on slips of paper and put them in a bucket, which the teacher then distributes to each of the students buckets at the end of the day. I personally thought that there would be days that some students would get none or very little while others got a lot, but she says that everyday everyone gets about the say amount.  Is this something you have used or would consider using in your class?
This experience has taught me a lot about setting up my future classroom and different techniques I can use in my room.  Any other tips or ideas would be greatly appreciated.
