HowToSaveMoney.me provides budget tools, worksheets, and calculators to help with personal financial literacy. For example, an investment calculator shows how a little bit of saving goes a long way when added up over the years.
The site also has an education section for students and teachers. This page features a collection of online quizzes and illustrated problem sets dealing with money. Choose a quiz, enter the answers into the box, and click “grade” when finished. The difficulty levels range from easy to advanced.
