Math lessons by topics of interest to students:

Car Payments - a lesson for grades 9-12 which has students access a used car lot on the Internet and then select a car from the free buyer's and seller's service. Students will calculate monthy car payments on "their" car, using formulas with complex fractions and large exponents.

Cellular Phone Service - an excellent example of a real-world problem using systems of equations. Students are asked to make a numerical, tabular, and graphical analysis of three different payment plans for a cellular phone. (Used in the PUMP algebra curriculum)

Get Rich Quick - Is it better to be given $1000 a year until you're 21 or $1 one year, $2 the next and so on doubling the amount you get each year until you're 21? In this lesson, students compare linear and exponential relationships and later apply their knowledge to a study of world population growth.

Maximum Trajectory - a fun, outdoor lesson using a garden hose to find the optimum angle for shooting water to achieve the greatest horizontal distance. Students are also asked to apply this to the track team and the angle from which a shot put or javelin should be thrown to achieve maximum distance.

Photograph Math - a lesson in which students can click on any of 14 different photographs and then answer a series of questions about the objects in the photo. Mathematical skills involved include recognizing patterns and geometrical shapes, estimating, and calculating areas.

Prom Date - a lesson in which students use information from the Internet to calculate the cost of a prom date. Eventually, students will graph the costs for all students in the class and find the mean, median, and mode of this data.

Stock Market and Lottery Math - two lessons enabling students to examine various ways to invest money and the risks associated with each. Students will be able to calculate commission for a stock transaction through a broker using the relationship between percentages and decimals, decide which stocks are preferable based on the price to earnings ratios listed on the stock market quotes, and use fractions and decimals to calculate the cost to buy or sell various stocks according to the stock market quotes high and low listings. They will also calculate the odds for different investment strategies.
