Math
In the last two Math Mondays, we covered exponential growth and decay. This week, we’re shifting slightly to exponential functions’ fun neighbor - compound interest.  Compound interest is a rich topic with abundant real-world applications. Today, we’ll highlight three fun classroom activities that will help your students master compound interest, followed by some additional extension activities. Activity 1: Compound Interest in Savings Accounts The lesson MATH: Compound...
