This is the first thing I do with my first graders on the first day of school. I model it first with my classroom aide and myself.
Students are paired up with a classmate. They are given a pile of pictures and a Venn Diagram. They have to chat to find out who did what activities over the summer vacation. They glue the picture on where it belongs.
My students LOVE this activity every year and it seems to start off on a great note of communication and teamwork.
