Great to help students figure out what to write about. I have this posted in my writing center, and each students has a copy on the inside cover of their writing journals.
I created this after realizing that my students biggest struggle with writing what figuring out what they could write about. This provides them with many ideas to help them get started.
My students do independent writing weekly, where that don't have a prompt and can write about anything they want. This has helped reduce the number of times that I hear each student ask "what can I write about?' or hear them saying "I don't know what to write!" Which in the end has given me more time to simple monitor the writing, or work with students who need more one-on-one help.
