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.
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.
Anytime I can bring a student up for a demonstration it usually captures the other students' attention much more than I do. Having a physical connection can help with internalizing the mathematics.
I use the School of One online dashboard on my computer to monitor real-time student progress on digital content. When I notice patterns of errors and/or clear misconceptions, I approach specific students for one-on-one Targeted Interventions. This strategy allows me to correct misconceptions in real time.
