The best way to build creators is to make technology authentic--a tool rather than a stand-alone skill. This does mean becoming knowledgeable on what core classes are teaching--their curriculum and lessons--and then blending with them. You'll pick skills students are capable of so students aren't intimidated or discouraged. I scaffold the learning of skills (like image editing and slideshows) over a period of years, using class lessons to build student knowledge.
There are lots of lesson plan websites out there but they don't necessarily tell you how to prepare students to use technology naturally, without tears. That's why I created my K-8 tech curriculum (https://www.structuredlearning.net/book/k-8-tech-curriculum-set/) -- so as a teacher, I could scaffold learning and support school mission.
Does that help?
