In my lesson plans, I have each day planned out, but the lessons are planned with the end in mind like a 5-day unit. The lesson one day feeds into the next lesson and we continue to build upon prior knowledge. Each day, I follow the steps of explicit instruction (introduction, presentation, guided practice, independent practice, closure), but we are building on previous lessons. I have an assessment daily, but it may be as simple as using individual white boards to work problems as I monitor. It works well in my class at the elementary level. I plan each day, but I plan it as a whole unit, not just as an isolated lesson.
