This activity gives students a chance to take pieces of evidence and form a hypothesis. In the teacher instructions you start out with a sentence that you will cut up into its word pieces. Groups of students are given the pieces, but are only allowed to look at a few at a time. The students then work as a group to try to come up with the original sentence, as more words are slowly revealed to them. I got the inspiration for this activity from another teacher's website, then created my own so that it was better suited and more detailed for my students. It is a great activity for group work, critical thinking, understanding hypotheses, and its just fun! My students always get big kick out of comparing their group's sentences to everyone else's at the end of the activity.
