Whole Group Discussion
During Live Investigation and Task sessions (both teacher-led), I often use a whole group discussion format just like a traditional classroom. Blended or not, there is no substitute for discussion.
The core ideas of my classroom are big ideas and themes that run through almost every lesson I teach. They are good math values, work values, life values. Whenever they come up during a lesson, I always explicitly make the connection. Next year, I plan on using a graphic for each value (some kind of eye graphic for core idea #1) to show, in my lessons, where the ideas come up.
I frequently have my students play games as part of their learning sessions. Many students only want to play the games and do not think of creating a written records of the problems they are solving or notes on their learning. I ask my students to "split the difference" and go 50/50 on playing and note-taking. It's kind of a misnomer since there really is no "difference" to split, but the strategy makes it clear that my students should be splitting their time equally between playing a game and taking notes during that game.
Since I work with 3 large cohorts of 6th, 7th, and 8th grade students (100+ students in each cohort) my colleagues and I developed a Town Hall Meeting for the beginning of the year to explain our Rules, Routines, Procedures, and Consequences to the entire cohort at once. Having all of my students on the same system has provided tremendous consistency and stability and created a solid community foundation. Town Hall Meeting is a place where students not only hear the expectations but are encouraged to ask questions or make comments to the entire community. Delivering this presentation once to the entire cohort helps to set the culture in an efficient way.
