I teach Algebra 2. My curriculum is divided up into 4 classes, each with 3 units. The students that take my Algebra 2 classes generally need the extra time to process the content. For my Trigonometry Unit, I have found that the Law of Sines and Law of Cosines Look-up Tables are successful tools. These tables essentially takes the Law of Sines and Law of Cosines formulas and solve for all possible variables. Students fill in their own blank sheets (included). Discussions that follow involve identifying patterns in the tables; deciding which function should be used for a specific problem; and, of course, why are these tables more work than they really need to be?
