Option 1: Create a resource (poster, video, presentation slide, document) that explains either decomposition, abstraction or computational thinking in general. Explain who your target audience are (teachers for PD, Year level, public).
My target audience is upper primary years 5, 6 and 7. My poster details a description if decomposition. It also provides a few picture examples of decomposition and a written example. It is clear and easy to understand.
