Reflection: Perseverance Exploring the Idea of Division - Section 2: Opening Activity and Discussion

The trick to this lesson is to be sure NOT to jump in and give them The Answer or tell them that an approach they are taking won't work.  It may puzzle the students that you won't assist them in their thinking but it's a good practice.  It demonstrates to them that you truly believe that sometimes it's okay for them to just explore their own thinking about a process.  This lesson is very simple, very open-ended, and leads to very complex thinking.  It's fascinating to watch the different diagrams students will develop as they attempt to divide the bananas into equal pieces.  The way their thinking develops with each successive attempt provides a lot of information about how developed their understanding is of how to split things up, how to skip count, and what the term "equal" truly means.
