Exponent Activities in Algebra 2
The Internet offers a wide array of teaching tools for exponential functions. There are videotaped lessons that offer an instructor using traditional boards and pens to exemplify functions, while other offerings include games and problem-solving activities. Some of the resources given here have graphics which are sophisticated and reflective of the scientific community, while others have cartoons and playful graphics to get their message across.
An assortment of entertaining and engaging interactive problem-solving strategies can make learning exponents fun and can embed the material in a more solid manner when students are playing with the material, not just passively listening to the instructor.

Cool Math's website offers exponent lessons in a cartoon fashion, with easy to understand language, graphics and navigation. Cool Math has both pre-algebra and algebra level exponents pages. On the pre-algebra page, kids learn what exponents are, as well as how they work, including the use of negative exponents. On the algebra exponents page kids can learn more complicated rules of exponents, along with a review, and are offered a wide range of exponent practice problems to solve. There is a fun "Exponent Game," which is free online, where you guess answers for exponent problems with a little troll character guiding you. BasketMath throws exponential computations up for you to compute and when you answer correctly, a basketball player shoots a basket. Math.com also offers exponent practice games with automatic answers and peeks.

Online Math Learning offers nine webpages of video presentations which teach about exponents. There is an introduction to exponents video series, as well as videos about graphing exponents, applying exponential functions and solving exponential equations with same and different bases. These videotaped lessons provide online instruction with a visual component. There is also a series of videotaped lessons on logarithmic functions and how they function as the inverse of exponents, along with other lessons that link the two topics. Mrs. Glosser's Math Goodies offers a clear and concise lesson on exponents and how they work, followed by interactive questions about exponents with online answers provided. There is also an exceptional interactive exponents review online by S. Waner, which integrates a review of integers with questions accompanied by peeks and answers.
