I've just been introduced to STORY SPINE, a good and easy way to remember how to plot a story. Especially useful for picture books:
From theater educator Kenn Adams -- to teach the craft of story structure.Kenn is a veteran improviser, a playwright, and the author of How to Improvise a Full-Length Play: The Art of Spontaneous Theater. He’s been doing school theater enrichment programs for 20 years. The Story Spine exercise is one Kenn uses not only with kids, but also with adults in improv classes.
