This is a free online tool that will be very useful for illustrating democratic decision making. Once a question is posed children (or adults!) can post a proposed solution or argument for or against an idea. Then everyone votes for the best idea. Not only do children enjoy posting, but the site lays out the argument well enabling them to think clearly before casting their vote - which again they love doing on the computer. So, next time you have a class decision to make whether it's what topic to study, or where to go for a trip, try tricider.
