There are 13 proofs that are put in a puzzle format. Each proof contains the diagram, the given and what is to be proven. Also, a two-column style answer space. These are all fixed objects on the page and cannot be moved. All the statements and reasons for each particular proof are movable and can be put into the appropriate column and number. It is a nice interactive lesson where the students can get out of their chairs and use the Smart Board and drag the answers where they think they belong.
