One of the best ways to write so that readers can imagine what you are writing (imagery) is to include sensory details.
First, pick your mood.
Then, choose words to describe what your character can see, hear, smell, taste, and how things feel to the sense of touch.
When I teach students how to develop characters, I use the STEAL graphic organizer to describe the character all throughout the story and sometimes to show how the changes.
Make sure that the words you choose match the mood that you chose for your story!😊
S - what the character says
T - what the character thinks
E - the effect the character has on others/how the character gets long (or not) with others
A - actions the character takes
L - what the character looks like
Good luck! And have fun with the assignment too!
