I teach high school Econ, but it’s very basic and relies heavily on content from before the Great Depression. What are some current theories an Econ 101 should include?

I focus on the basics; being a business, taxes, government spending - but I know that economics has changed beyond basic supply and demand/ rational actor. I just don’t have a sense of priority with more modern content.

I would just suggest a textbook? (Mankiw, Krugman-Wells, Goolsbee-Levitt-Syverson, etc.) Supply and demand is still very relevant, but most textbooks do have modern content (even if "modern" means "from ~10 years ago," that's still modern relative to "before the Great Depression")
