"The Visual Ranking Tool brings focus to the thinking behind making ordered lists. Students identify and refine criteria as they assign order or ranking to a list. They must explain their reasoning and can compare their work with each other in a visual diagram. This tool supports activities where students need to organize ideas, debate differences, and reach consensus. The tool and related resources are available for free, from any computer that is connected to the Internet. Students may work on their lists at home or at school, and can even compare their ideas with students located in distant classrooms. "
