After studying a specific letter and letter sound, students can use this "Read and write the room" (or "Word Investigators" activity to extend their understanding. This is a GERAT activity for students to use at Reading Workshop stations, the Daily 5, centers, enrichment, etc.
All students need is a clipboard and a writing utensil. Active participation and learning takes place during this activity. Not to mention it is the students most favored station/ (or center).
Also, at the end I included some digraphs and blends for students to practice and get familiar with. For example, "th", "sh, "ch".
