So one way you might teach it is by using a fun activity that is available via the web or in the book Reading, Writing, and Rising Up (Linda Christensen). The point of the activity is to get people to talk about who they are so there can be bigger conversations about things people have in common. The activity is called 'I am From' poems. The students (and you) would come up with a variety of things about them... Things they hear a lot, items in their life, important people to them, etc. You would also write and share and the kids would do the same. After each person goes you could allow questions to be asked. If you have an end of day scheduled with parents, this would be a great way for you to get it and also allow your families/students to ask questions.
