If anyone isn't familiar with this activity, you can find the instructions and worksheet here.
This activity gets students super excited about doing math, while doing math in the process. The activity includes completing a table of values, creating a scatterplot, finding the line of best fit, finding the equation to the line (slope, y-intercept...) and predicting the number of elastics needed so that the barbie can jump off of whatever ledge you choose in your school without hitting the floor.
I have tried this activity twice in my classes: once with a class of grade 9 students and once with a class of grade 10 students. These are my observations, and tips on how to implement this activity in the classroom so that the students are focused, and everything can get done on time.
