Ask the students to think of a favorite character from a book, TV show, or movie. As the students name each one, ask them to consider why the characters are so memorable. Make a list of the traits as students list them -- they might come up with things like brave, funny, etc. Tell the students these are the same traits that they should try to include in their writing.
Show the slide with the stock images of different people. The students will pick one that they might see as a character in a story. They should first name the character and then come up with a list of character traits. Students can also add biographical details to the list (job, family, etc.). After making the list, students should draft a brief character summary.
The teacher can do an example as a model for the students. Also, you can choose a few students to share their ideas aloud with the class for more examples.
