Mine love this: Have them hold a certain color, or animal finger puppet, or object and tell a story...each time that object is said they get to hold it up and shout it! Or, you could tie in a craft with a story: Craft is making butterflies; then you read all about them (you could even make some magnifying glasses/butterfly nets and go pretend exploring for butterflies). Also, my group loves action stories that get them up & moving throughout.
