This is a great end-of-year activity before the CRCT (Georgia) or other standardized testing activity, or it can even be used before a classroom test or assessment as review. (Please message me / send me a "question" if you'd like a version that doesn't say "CRCT" at the top.)
All you have to provide is sample test questions - and you only need a few. The students get grouped in teams of 4 and each member is given a role. The students are walked step-by-step through good test-taking techniques and then must defend their answers to the class.
There is also a participation rubric attached for grading / scoring.
