Here are some of my favorites:
Create a set of questions related to a topic of study. Write them out on chart paper. These questions will be used as brainstorming sheets for a pre lesson assessment, and then again for a post lesson assessment. Group students at one of the chart questions and have them discuss and record ideas. Upon a designated signal pass the charts to a new group and continue the same process. Each group will respond and add to all question charts. The neat part of this is if you do the same questions as a post Carousel Writing you can see growth in ideas. The samples below were for a science unit on Living Things. The pre lesson Carousel brainstorming was in red and the post lesson was in green.
This idea comes from the book Getting Into Words by Shira Lubliner.
