This resource is a great way to introduce and reinforce the concept of main idea. Print and cut out items and place in bags. Students will work in partners or small groups to look at the items in the bag, and come up with the main idea. Included are slips of paper with directions and a place to write the main idea. This activity allows students to have hands-on, applicable practice with main idea, and is a great lead into talking about supporting details as well.
