ESPN's 30-to-30: Broke is a documentary about sports stars who went from having millions of dollars to being broke. It discusses why this happens and how many lacked basic financial skills. It pinpoints the missing skills. This worksheet helps students see that it does not matter how much money you have if you use it wisely. I have used this movie guide for substitute plans since it generalizes financial principals. I always use this in my financial math classes. Students like the documentary an

I use this project with my students at the conclusion of the linear regression unit. I use local weather data and ask them to create a scatter plot, find the line of best fit, find the correlation coefficient, create a residual plot, interpolate and extrapolate data. The answer key is included.

Students plot the given points to make 3 different parallelograms in the coordinate plane. They must show the given theorem to be true that shows the quadrilateral is a parallelogram.

A set of 3 labs from Function Junction. Each lab contains a table, a grid to plot data and follow-up questions to walk students through the linear regression analysis. Questions include equations of the line of best fit, correlation coefficient, residual plots and extrapolating data.

In my financial math classes, I find current event articles related to our current units. However, in the Investment Unit, I require them to find one and review it. I give several websites for them to find articles, read and review them. This worksheet leads them through the process. Created by Function Junction.

This lab uses angle-angle similarity to indirectly measure objects. By Function Junction.

In this math lab students fold and tear paper to model exponential growth and decay. There is one activity for growth and one for decay. After recording their observations, students are asked to write exponential equations and use them to extrapolate information.

This worksheet created by function junction, has students research the terms associated with leasing a vehicle. It also has students compare monthly payments to buy the vehicle.

Students place their "ships" on the cartesian coordinate plane. Guideline for ships are on the worksheet. Students will work in pairs to guess the location of each other's ships. I usually give each student a manilla folder to hide their papers from their opponent.

This worksheet has students plot given points of a trapezoid. Then students must use midpoint formula to find the coordinates of the midsegment. Next, they verify that the segments are parallel using the formula for slope. Then they must use distance formula to verify the length of the midsegment.

After trying to get my students to do things that would help them solve word problems with little success, I created this table, similar to a Frayer Model, for students to complete when they answer word problems. It helped many of my students and many would draw the table by hand when I did not provide them as a handout. I type the problems in the middle box and they complete the sections around the problem.
