Khan Academy: Algebra: Word Problem Solving Exponential Growth and Decay

Quiz your middle and high schoolers on solving exponential growth and decay. First, they evaluate for a variable given the second variables value. Then, they graph an equation that illustrates the exponential growth or exponential decay...

How can you safely model exponential growth and decay? A hands-on activity uses candies to model not only exponential decay, but also exponential growth. Exponential equations are fitted by hand and by use of a calculator...

Start with the basics and move up the exponential ladder to master a variety of problem-solving and application problems. The problems are heavy on exponential growth and decay, compound interest, and natural log.  

Learners differentiate between exponential growth and decay. In this algebra lesson, students solve exponential equations using properties of exponents. They use the Ti calculator to graph and analyze their functions.

Concepts from the last few videos, particularly exponential growth and decay functions, are covered in this video about word problems. Viewers can apply their new (or growing) algebraic knowledge to solve the word problems along with Sal.

This video focuses on three word problems involving measurements, percentages, and expenditures. Sal shows how to translate word problems into solvable equations.

A video that demonstrates how to write and solve equations for several different types of algebraic word problems. This is another percent example. This video is also found in the strand Algebra: ck12.org. [11:06]

Good site explaining exponential growth and decay, with questions for students to test themselves.

Find material to use when planning instruction on exponential growth and decay. A lesson offers several examples, graphs, and explanations, and there are two practice exercises and a group activity for testing and applying concepts learned.

Does this word problem describe exponential growth? Is something increasing? Is it increasing at a constant rate? How much is it increasing? Use the function formula for exponential growth to figure out this problem.
