The guided notes will explain to students what suspense is, the elements of suspense, and how to build suspense within writing.
I followed up the guided notes with practice. The "Identifying Elements that Build Suspense in Writing" is the follow-up activity on my TpT store. I think you'll find this an effective activity after the guided notes.
Additionally, I have a rubric on my TpT store that allows the students to grade their own suspense writing and determine their grade. I have the students complete the rubric first before I grade the writing.
