This is a very extensive list of writing prompts. There are over 250 prompts and they're broken down into categories. I often use writing prompts or journal topics to start my class. (I call this a do now but other people call it a bell ringer.) You could also assign writing prompts for a homework assignment or for students that finish their work early. Here are a few examples:
How do you feel on the first day of school?
I wish I had a million... Then I would...
What does "The early bird gets the worm" mean to you?
What would you do if you saw a friend cheating--report it, confront the friend, nothing--and why?
There are more than enough writing prompts for the entire year. In fact there are so many prompts included here that you can pick and choose the prompts you want and still have enough for a daily writing assignment.
I've enclosed the CCSS for grades 5-12 for your convenience.
There are two formats enclosed here: MS Word Format and PDF format.
Please look at the preview and if you have any questions ask.
I have the same writing prompts in Task Card Format listed here:
