Use a yard stick (or meter stick) to encourage deep thinking. Place a sports band, wrist band, hair band or rubber band around the stick. Ask two students to hold either end level. As other students share ideas, questions, etc. have the group evaluate the depth of the comment. Move the band to indicate the depth, encouraging students to dig deeper.
