The Writing Exercises site has a number of prompts to support the writing process.
Check out the following resources for use in the classroom:
From the Children’s Section you can access a number of images in which learners can develop their descriptive vocabulary using images.
The Odd Objects section provides a stimulus for discussion which can lead to the writing process.
You can also generate a Random First Line of a story in which learners can continue.
The Random First Line Generator can spark the beginning of a short story which can be further developed by learners.
