Unit 4, Lesson 22# Writing and Evaluating Expressions--Exponents

EngageNY 45 min(s)

Students evaluate and write formulas involving exponents for given values in real-world problems. Other examples of exponential applications involve bacterial growth (powers of 2) and compound interest. If time permits at the end of the lesson, a larger sheet of paper can be used to experiment further. Ask students to predict how many times they can fold a piece of paper in half.
