Keep the main problem and the most important actions and results. Leave out small details and do not add results the passage never reports.
Worked example
A summary of a playground cleanup should explain what needed attention and what the group did, rather than list every person's clothing or snack.
Books Back in Action
Several shared classroom books have torn covers or loose pages. The class sorts them by the repairs they need, using a green box by the window. With the teacher's help, students mend small cover tears and secure a few loose pages. Books with damaged bindings go to the librarian for advice. By Friday, nine books are back on the shelf. The class makes a sign reminding readers to turn pages gently.
