Math Monday: Solving Equations and Loans
Solving equations is a high-leverage math skill that can take a lot of practice for students. In today’s Math Monday, we’ll cover one more activity for you to have ready the next time you need to review solving equations.
In MATH: Loan Repayments Using Simple Interest, students practice identifying key values from word problems, substituting those values into equations, and solving for a variable.
In the Edpuzzle video, Abby breaks down how to calculate the cost of buying a laptop using a credit card and paying it off over 6 months.
The practice problems build in complexity, from calculating the total interest paid to calculating the interest rate and time frame, which requires solving for a variable. Finally, students reflect on how interest rates impact the cost of their purchases.
