"What is a Mystery?" and "What is the Crime?" are two engaging videos that are a part of "The Ultimate Mystery Writing Course for Kids," a series of engaging, easy-to-follow lessons I created for udemy.com, in which I take young writers step-by-step from the beginning of the writing process to the end and help them craft stories that keep readers guessing and on the edge of their seats!
If your child is interested in writing a mystery adventure, you may also want to consider "The Ultimate Mystery Writing Guide for Kids" on amazon.com.
In both the course and the guide, I combine the knowledge and skills I have developed during my 22-year teaching career with numerous examples from my Chase Manning Mystery Series to teach children about crimes, crime solvers, suspects, motives, clues, witnesses, alibis, red herrings, and all the other elements that make mysteries so much fun to read and write.
