I noticed that students both needed and wanted a quick and engaging introduction to content. Instead of simply asking what do you know about this topic students prior knowledge is activated through a often funny yet very informative video segment on a topic. These videos are great for introduciing Social Studies content because they take often large and abstract topics and make them accessible for students.
Formal transitions happen twice during a double-block period. My students have to move from one section of my extra-large classroom (3 classrooms merged into one) and move to another section for a new lesson with a new teacher. My students have two minutes to transition from session to session, and we play a variety of interesting music on the surround sound stereo system to keep it fun.
TOAST is an acronym that stands for "Time Owed After School Today." It's a very simple and non-punitive consequence that we implement for students who don't follow the rules: 1) Respect all people, property, and ideas; 2) Follow directions the first time; 3) Be prepared. I make it very clear at the beginning of the year that TOAST does not mean I'm mad at you or that you're a bad person; however, there are consequences for your actions that are not consistent with our community expectations. Paying with time and doing some community service or making a plan to change student actions have been effective ways to turn negative student behavior into a positive.
At the end of every class, my students must take a computer-based exit slip. This is an essential part of my blended program because these exit slips tell me whether or not my students are ready to move on to the next skill. If a student gets 4/5 or 5/5, he or she can move on. If not, he or she will be assigned a different type of lesson on that skill the next day.
