As a classroom teacher, I prioritize blocked lessons. I introduce some information, present it, and then check my students. This happens at least 3 times per class.

For a more smaller, personal, 1 on 1 tutoring environment the lessons are very relaxed and usually take the structure and format of a dialogue. The structure is very laidback and instead is dictated by the needs of the student. The lessons usually begin with a speaking practice (usually talking about the day, or the week since the previous class), discussion of material and practice, and then concludes with the assigning of practice/homework both for the student but for myself to plan for the next lesson.
