I have used interactive notebooks for about 5 years now. Students love having a place for their notes, they enjoy the organization, and they enjoy the 'easy' points when I grade them. I ask a lot of questions during the hour and always give the students time to think. If I will be asking random students for answers, I warn them that it's coming, ask them to write down their answers and check them with their group members, and THEN I randomly ask a student to share their "guess" as I call it (in case they're wrong). I try to keep my students from getting bored. Math isn't exciting for most high school students so I try my best to keep my class light and as fun as I can.
