Ahead of time we brainstormed common feelings such as excited, happy, angry and also feelings that might not immediately come to mind, such as jealous and embarrassed.
Using the iPad camera pairs of students photographed each other acting out 4 different emotions. They took just head/shoulder shots so the focus was really on the face. At this point I gave students a choice. The first option was to import photos to a 4 panel Strip Design where a speech bubble was added that explained the feeling and why they were feeling that way. The second option was to import photos into StoryBuddy and create a 4 page book, with text explaining the feeling and the reason behind the feeling. There was a pretty even split between the 2 options. Since we are working on "expanded" or "super" sentences in second grade, part of the assignment for those students was to write a very detailed sentence.
An example of a first grade sentence "I felt tired because I stayed up late."
An example of a second grade sentence "On the playground at recess I felt lonely because all my friends wanted to run quickly on the soccer field instead of sliding on the tunnel slide."
