This year, I switched up the order a bit in Algebra 1 and moved creating scatter plots and lines of best fit from our Data Analysis Unit (end of the year) to our Linear Graphs and Inequalities Unit (half way …

This hula hoop scatterplot activity gets students moving in math class while learning about how to create a scatterplot and use that scatterplot and linear regression to make predictions. Five or so years ago before I ever started teaching, I purchased a hula hoop at a yard sale.  I paid a whopping 10 cents for …

I learned about using twizzlers for linear regression from Tammy Ballard with Wake County Public Schools. I modified her activity to create my own twizzlers linear regression lab that met the needs of my specific group of Algebra 2 students. The idea is simple.  Give students a twizzler to eat.  Before students take a bite …

I learned about this bouncing tennis balls linear regression lab through the OGAP Common Core Training I attended this summer.  It is based on an Illuminations activity from NCTM.   Students are given a tennis ball to bounce for two minutes.  Every ten seconds, the number of bounces is recorded.  I learned a lot from …

I want to share a linear regression activity I did with my Algebra 2 students to introduce the topic of regression. I combined linear regression with the True Colors Personality Test that I had originally wanted to do with my students at the beginning of the year. The summer after my first year of teaching, …
