Loan Investigator: Unraveling Interest Rate Impacts

Grade 8Math5 days
The 'Loan Investigator: Unraveling Interest Rate Impacts' project is designed for 8th-grade math students to explore and understand the influence of interest rates and loan terms on financial decisions. Through hands-on activities such as digital storyboards, interest rate simulations, and role-playing financial scenarios, students learn to calculate loan repayment costs, differentiate between simple and compound interest, and evaluate financial responsibility. The project emphasizes the importance of using mathematical processes to make informed financial choices and fosters critical thinking about long-term personal financial goals.
