Storyboard That is a service that you and your students can use to create simple comic strips. I've reviewed it in the past and today I would like to share a demonstration of how to use it. The video below demonstrates how to use the basic functions of Storyboard That.
Storyboard That has free and paid plans. The free plan allows you to create three and six frame stories. The free plan also limits you to three storyboards per week. A paid classroom account offers options for managing student accounts, limiting sharing to classroom members only, and a classroom account offers more frames per storyboard.
