Function Junction

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.

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 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.

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.

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.
