Reflection: ELL Students Solving Basic Trigonometric Equations - Section 2: Explanation

 

For students who struggle with drawing their rotation diagrams and determining their solutions to the equations I would recommend showing individual teams or students another example with colors. I found that they were really able to see it all better when I walked around with a little whiteboard and drew in the axes in one color, the angle for our solution in one color, and then the reference angle in another color. Also, for students who feel uncomfortable with math and are not feeling confident remind them they can check their answers. Some of my students did not make this connection on their own so I had to be sure to explicitly tell them.
