Definitely going over the difference between W-2 employees and 1099 employees. A lot of people are doing side hustles like door dash and uber, but don't understand how the taxes work on those 1099 jobs. They end up in a mess come tax season.

Maybe a lesson on cost of making just one meal. Last summer I sent each one of my 14 year old twins to the grocery store with $25.00 and ask them to buy food to prepare a meal for our family of 4 to eat that night. They had to come up with a meal in their head, find the ingredients and do the math to make sure they stayed in the $25.00 budget including any taxes. They both came home stating that was really hard to figure out what made a good meal and what food actually costs just for 1 meal for a family of 4. We had pasta with garlic bread and salad for one meal and the other did tacos/quesadillas with spanish rice. It was a very good learning lesson for them, especially when they complain that I didn't get something they wanted at the store when I shop.
