 4.3 Trig Ratio Row Game

Students were grouped in pairs. One student answers question from column A, the partner answers the question from column B. The questions are different, however, the answers will be the same. If the answers do not match, students must work together to discover the error and determine a correct answer. If you try this activity, stand back and listen to the mathematical conversations between students as they work together. Many students use correct vocabulary as they explain their processess.
