Here's what I did:
I had already read aloud Big Al by Andrew Clements during the first week of school. We watched how Big Al, the ugliest fish in the sea, tried many things in order to fit in. Finally, when a fisherman's net captures many of the fish, he saves the day and gains a sense of belonging. He has the most friends of all the fish in the sea.
Tuesday/Wednesday: Read aloud Babushka Baba Yaga by Patricia Polacco.
Thursday: We watched The Lost Thing and discussed what we saw in the video and how it related to belonging. (There is SOOOOO much to talk about in this video. I could do an entire week of lessons just on it, but I mostly stayed focused on the idea of belonging in this lesson, knowing that I would be able to go back to it and use it later for other things. For example, why is "the lost thing" a lost thing--who says he is 'lost'? Is it really lost? Do we have to find others like us (or assimilate) to gain a sense of belonging? What does "the lost thing" symbolize? etc. This is a rich video for "close reading" lessons! It is also sending a message about individuality in a society of sameness, so I plan to use the video again during our Individualism theme.)
Friday: We have met many characters this year that have tried to belong (especially this week with it being our theme focus), so it was time to start comparing our story lines and identifying generalizations. Students work to fill out this chart and then we created a class chart on the smartboard.
