The document discusses anchor activities, which are ongoing assignments and tasks that students can work on independently after completing their main assignments. Anchor activities are used to occupy students' time productively during "ragged time" when they finish work at different paces. Suggested anchor activities include journal writing, vocabulary work, spelling practice, and silent reading. The document provides tips for implementing anchor activities, such as clearly teaching expectations and tasks, and assessing student work through checklists, conferences, and rubrics.
