EssEntial QuEstions

How does being financially literate help you manage your money?

How can you plan ahead for future financial goals?

Unit OverviewBeing financially literate means taking responsibility for learning how to calculate income taxes on wages and how to create a budget to plan your spending and savings. Using a budget estimator will help you look at monthly earnings and expenses. You will also learn how to look ahead to long-term savings for future needs. Creating a net worth statement will help you see how families evaluate how well they’re doing on their financial goals. As you continue through the unit, you will apply what you have learned to solve real-world financial problems.

Key TermsAs you study this unit, add these and other terms to your math notebook. Include in your notes your prior knowledge of each word, as well as your experiences in using the word in different mathematical examples. If needed, ask for help in pronouncing new words and add information on pronunciation to your math notebook. It is important that you learn new terms and use them correctly in your class discussions and in your problem solutions.

Academic Vocabulary• income tax • sales tax• property tax • take-home pay• budget • fixed expense• variable expense • net worth• assets • liabilities• compound interest • monetary incentive• coupon • rebates
