Here is a collection of 35 weeks of Bell Ringer writing prompts for HS ELA classes (including AP English Language and Composition and AP English Literature and Composition).
Each week, students focus on a single quote from a writer from one of their books or a speech they made. Each day of the week the students write to a specific prompt and end with some analysis writing at the end of the week. This is a very powerful tool in developing thinking and writing and reasoning skills.
Note: These are real quotes. The internet is flush with incorrect quotes and attributions but these are all legitimate and come from my own reading, not google searches. If nothing else, you are paying for my list of interesting quotes from what I read, which is worth the small price.
Also, if you would like to focus on excerpts I've selected from Literature, select my other Bell Ringer ppt called 40 Weeks of Literature Bell Ringers - Analytical Writing Strategies.
