Guided Practice
As we explicitly teach a concept to our students, it is important to remember the phrase, "I do, we do, you do."  This phrase is meant to remind you to include guided practice and gradual release in your lessons.  A teacher cannot expect a student to complete a skill perfectly.  If we model for the kids, work with the kids, and then have the kids work independently, the students are more likely to master the concept or skill that we're expecting them to learn.

Take a look at this video that shows the gradual release of students during a writing lesson.
