Opportunity Cost
Every choice has a hidden cost, called the opportunity cost. In this lesson, students evaluate trade-offs by identifying the next-best alternative they give up when making a decision.

Setting S.M.A.R.T. Goals
A goal without a plan is just a wish, and most wishes don't come with price tags. This lesson introduces the S.M.A.R.T. goal framework and connects it to real savings strategies so students can turn vague financial intentions into actionable plans.
