The document summarizes four days of a fourth grade writer's workshop. The lessons focused on: 1) analyzing student essays to determine the message or thesis, 2) using questions to develop a thesis statement about a research topic, 3) planning the essay structure with reasons to support the thesis, and 4) adding personal experiences and facts to support each reason. The workshop aimed to teach students how to write an effective expository essay with a clear thesis statement and evidence to back it up.
