I'm a financial writer, but I'm not teaching my teenagers about investing. It's hard to get excited about stocks before you have an income.
Briefly

When people don't have any income, it's hard to get too excited about investing. Investing might feel unnecessary for teens without steady income or employment.
Young people who are just getting started in life might not want to bother with the volatility and risks of the stock market; just build up your emergency savings fund first.
I doubt that most practical 'adult life' advice about personal finance will feel relevant to teenagers, and a 2013 analysis of research backs this up, finding that financial education had 'negligible impact' long-term.
Instead of investing in stocks, I would encourage my kids to just save extra cash from their part-time jobs in a high-yield savings account.
