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.
In addition, the education page includes links to visual reference materials on US currency and world currencies.
