Check out Part 2 of my previous post, "Prompts to Pump Up Creativity and Imagination." The upcoming "sparks," all crucial areas in education, don't get enough time in our classrooms. They can be used in various ways: a "wake-up call" in the morning to get students thinking and feeling. The prompt can be written on the board or said orally to students. Give them a minute to understand what the statement, question, or "equation" means. Add another minute for reflection-and-thinking about their interpretation. Follow up with a class discussion about the prompt and all its associations, connections, meanings, and practical applications in everyday life.
You might want to add writing to this mini-lesson. Instead of just discussing the prompt with students orally, ask them to write a short paragraph response to it. Follow up with kids reading their responses to classmates and discussion. They would think about and reflect on the prompt's meanings, associations, connections, as well as their practical applications in everyday life, and write out their answers. It all culminates with students' oral readings and a class discussion.
Note: The mini-lesson should not exceed 30 minutes. Scan the different prompts and see which ones would be suitable for your students. This would work for upper elementary/middle school to high school students.
