Make Beliefs Comix, a multilingual comic strip creation service that I've featured in the past, recently released some new printable comic strip templates. These printable templates are in addition to the online Make Beliefs Comix creation tool. The templates are divided into dozens of thematic categories including history, holidays, and civil rights. There is even a category of templates titled Emotions which is designed to help students express how they are feeling through comic characters.
Applications for Education
The printable templates from Make Beliefs Comix could be excellent resources to use as creative writing prompts. You could have students start a simple story by using the templates then expand the story into a longer narrative.
