Launch, Explore, Discuss

At the elementary, middle, and high school levels we use a "Launch, Explore, Discuss" lesson structure which allows us to build class routines for exploring a rich problem in a student centered way. The launch, explore, discuss framework forefronts student thinking and supports understanding and discussion of student problem solving strategies (as opposed to procedures, answer getting, or speed). Discussion of mathematical ideas is student generated and situates students as the mathematical authority in the classroom.


A launch, explore, discuss lesson structure is also used in Cognitively Guided Instruction (CGI). CGI is a student-centered approach to teaching math at the elementary level that starts with what students already know and builds on their natural number sense and intuitive approaches to problem solving. When we use a CGI launch, explore, discuss lesson structure we focus on understanding student thinking, asking smart questions, and supporting students in listening to and thinking about each other's ideas.
