This activity is great for getting the kids up and moving while they learn about Main Ideas and Supporting Details. I would cut out each word or sentence and put them in a bag. Each student will pull out one slip of paper and when all the students have one they have to go looking for the other people in their group and determine who the Main Idea is. When they have figured that out they need to grab an "Umbrella" (You could bring in real umbrella's or just print out a picture of an Umbrella for students to use). The person with the Main Idea will hold the Umbrella and all the others who have supporting details will stand under the umbrella (or next to that person).
