I am just about done grading the exponentials and logs quizzes from today and my students did about the best they have ever done in the years I've taught Algebra 2. Here are a couple of things that I did that worked:
My version of Log Wars (with a reference to the loop for logs from Amy Gruen) - both of these worked amazingly well with my students. I could see that they understood what to do and could show me how to get the answers. My Advanced Algebra 2 students wanted to play Log Wars again.
Kate Nowak's approach to the Log Laws was also helpful. Students are still struggling with them, but struggling less than in years past. Still gotta work with this one some more to get it where I'd like.
