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.
Once a day twice during a two-week unit, students will come back from their individualized assignments and group as cohort. This gives them opportunity to take their assessments as a class as well participate in full class discussions, mentoring, study sessions, and peer to peer advisory.
