Writing prompts are a set of guidelines given to a student to help them analyze, practice, and learn how to write to a specific topic and audience. They are also a useful tool for teachers to help students learn how to go through the writing process and focus on specific writing traits.
An example for First Grade would be "Think about a day you will never forget. It might have been fun, exciting, or scary. Tell a story about this day to your teacher."
An example for Third Grade "Make up and write a story about what it would be like to be a pioneer in the 1800's."
An example for Fifth Grade "You have been granted your innermost wish! You have been transformed into your favorite toy. Tell what happens to you over the next 24 hours."
