I gave each student a sticky note labeled with a sentence type (declarative, interrogative, imperative or exclamatory) to place on their forehead. The students weren't allowed to look at their own label. Students were then encouraged to "mill" around the room and find a partner or actually several partners. They would then read the label on their partner's head silently and give an example of the sentence type. For example, if their partner's label read exclamatory they would say an exclamatory statement and their partner would then try to guess the sentence type label they had. Then they would switch roles and move on to other students.
At the end of the activity (after most students have had a chance to find various partners) each student would find their own label on the wall and form a group. Each group then explained to the whole class what their sentence type was, what kind of end mark it had and give an example. The kids had a blast! :)
