GEOMETRY TEACHERS: This is a great project to review the reasons (postulates, theorems, definitions) used in geometric proofs. I put the students in groups, have each group pick 5 reasons out of a hat, and then collaborate on a Google Slides presentation. For each reason, students have to define the postulate/theorem/definition in their own words, create an example using real life pictures/videos and then write the conditional statement, converse, inverse, contrapositive, and biconditional.
