Unit 6 of TEKS Financial Mathematics teaches students how credit works, how to borrow responsibly, and how debt affects long-term financial health. Students explore different types of credit—from credit cards to installment loans—and learn the true cost of borrowing by calculating interest, monthly payments, and payoff timelines.
They also examine credit reports and credit scores, learning how financial behavior impacts borrowing opportunities, housing, and even employment. By the end of this unit, students understand how to build, protect, and repair their credit profile.
