"Procedure:
Before students arrive, prepare the classroom, by moving the desks into a “secretary area” and leaving an open area for students to run back and forth. In the open area, post the sentence strips or story on the wall.
When students arrive, divide them into pairs.
Have one student from each pair sit with a pencil and paper. Have the other run back and forth between the sentence strips and their partner, until they have dictated the entire passage.
Emphasize that students must only whisper but not talk or yell.
You may need to remind students periodically that the runner can spell aloud, but cannot write anything.
If the sentence strips form a story, have the partners work together to correctly order the sentences.
Finally, have a volunteer read the entire passage while the other groups check their work."
