We covered the midterm exam today (40 multiple choice) in groups today. They knew their grade but not which problems that they got right/wrong. In groups of 5 problems, they tried to find the correct answers, and after a couple minutes of discussion for each group questions, I gave the answers and showed solutions for those who had questions.
Worked quite well. Lots of natural discussion and students helping students.
Next the students worked on finding trig graphs that went through given points. After fiddling with it on their whiteboards, they wrote down a set of steps to themselves in their notebooks.
Super interesting seeing the student thinking here. Will continue.
