French journal writing prompts are great for students in Early French Immersion or Core French classes. They are simple enough that they can be used in younger grades, but can also be used to get some longer responses out of older grades. This product includes over 100 prompts ranging from those you can use on an every day basis to those that are themed (e.g., Halloween, Christmas, etc.)
This is great to include in your Daily 5 Centres. I like to include a few prompts on a key ring that I change every month so that the students have choice in what they write about.
