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.  

If Sal has fifty dollars in his pocket and everything at the store is 25% off the marked price; What is the highest marked-price item he can buy? He also demonstrates what would happen if he invested $100 and gained 25% the first year,...

Sal uses some real life examples to explain percent gain. He also demonstrates how to convert percentages to decimal numbers in order to solve the problems.

Grow to review exponential functions. With the unit review, learners identity the type of function for given equations, such as exponential growth, decay, or linear. Pupils write the correct function for situations and then use the given...

They grow by leaps and bounds. Learners watch a quick review on function notation as they prepare to learn more about exponential growth. Using their knowledge from sequences, pupils find out whether a function is linear or exponential,...

Math can be taxing at times. With a short lesson, pupils determine how income tax affects take-home pay. Learners determine their net pay based on tax tables and how adjustments in their gross pay changes the paycheck.

Nine questions—multiple choice and fill in the blank—challenge mathematicians to solve money word problems. Looking closely at prices, scholars use a formula to identify percent increases and decreases based on an original and new price....

What was the original? Scholars learn how to find the whole when given the percent and the part in a percent problem. Eager learners use their skills to respond to several questions on a worksheet.

Solve two-step percent problems with a single multiplication. By reviewing how to find the percent of a problem, the video introduces the idea of finding multipliers to find solutions for increasing or decreasing percent problems. Pupil...

Increase or decrease the value. Individuals learn how to determine a new value after being either increased or decreased by a percent. Pupils then practice their skills using a worksheet that covers the concepts.

How much did it change? The presenter works two problems to demonstrate how to calculate percentage loss and increase. Pupils have one learning exercise to practice similar problems on their own.

Review a percentage of math skills. Designed to review for the General Certificate of Secondary Education Math assessment, the resource provides practice with a variety of percent problems. Items provide pupils problems ranging from...

Here's a resource that's rich with learning opportunities. Future mathematicians investigate the poverty rate in America over time. They use an interactive to compare the poverty rate during the Great Recession of 2008 to other years,...

Things are so expensive these days. A two-part video explains the concept of inflation and its ties to the federal nominal interest rate. Pupils then use data on the historical prices of items to calculate the inflation rates for several...

Increase your class's knowledge of percent change several fold. Viewers of an informative video learn how to calculate percent increase and decrease. They also see how to determine percent error and look at examples of each type of...

How much plastic do manufacturers use to create water bottles each year? The class explores the number of water bottles used throughout the years to determine how many consumers will use in the future. Class members compare different...

Statistically, waste may become a problem in the future if people do not take action. Using their knowledge of statistics and data representation, pupils take a look at the idea of waste generation. The four-part unit has class members...

An assessment presents a chart displaying oil consumption Pupils use the chart to determine the greatest increase in consumption, and then apply that information to figure out when the consumption may reach 100 million barrels a day.

How much money does the store make on the new sneakers you just bought? Use the video lesson to explore the formula for determining percent markup based on a selling price. The example shown explains how to determine a selling price...

Assemble a great lesson on assembly lines. In the first installment of a nine-part technology/engineering series, future entrepreneurs learn about the manufacturing process, specifically about the assembly line and cycle time. The lesson...

As part of a study of percent and percent change, learners first complete an assessment task with several percent change problems. They then complete an activity using cards to create a diagram expressing percent increases and decreases...

Half a foot difference may not mean much, but converting that to an 8% change puts it into perspective for young minds. The lesson discusses the idea of converting information into percents to discover errors made and how much it...
