Reader's Workshop
"In a reader's workshop the teacher begins by presenting a mini-lesson on a reading skill or concept. Students are then given uninterrupted time to read their various texts. Afterward students respond to what they have read in a reader response journal or reading log."

Writer's Workshop
"Writer's Workshop is the term most commonly used to describe the process of children choosing their own topics, writing, revising, editing, and publishing.  In Writer's Workshop, we try to simulate as closely as possible an atmosphere where real writers write and to help children see themselves as 'real authors'."
