Read then Write: Teacher gives some very simple and short messages. Students read, and then the teacher gives more questions so we can add more details to the story. Students write down the answers they create for the questions. Then add them to the story and recreate a more detailed story.
Just an idea here, since the final product is always a story, Ss can use the App book creator for the final story writing with illustration. Teacher can give the outline or structure in the app, so students can copy and paste, and start from there.
