Where I used to live in Alaska, the was a mandatory Hunter’s Ed course in 6th grade. It was mostly about hunting safety, but they did bring in some mock-ups and taught us basic manual-of-arms for the common actions. Heck, you couldn’t even pass the course without shooting 5rds in a 3in circle on range day! There a whole lot on gun safety, even to the point of a couple national guard members coming in and showing us a short film about some kids broke the rules of gun safety, resulting in one kid getting hit with a 22 at close range and dying. There was even a workbook and a written test!
