Above are a few strategies you can use to show your students how to add on to their narrative. First I would brainstorm a list with your students. Once you have brainstormed, create an anchor chart with them. It is beneficial for them to associate the strategy with a symbol like above. That way when they are editing their writing, they can draw a symbol showing what they want to add. After showing them these different strategies, show an example of how you use one. Below is the model I would use. I found a place where I needed to add more and so I would model how to write that with my students.
