Approximating a Line of Best Fit
You may be able to see patterns visually, but mathematics quantifies them. Here learners find correlation in scatterplots and write equations to represent that relationship. They fit a line to the data, find two points on the line, and...

Halloween Cartesian Art: Bat
Get the class batty over graphing. Young mathematicians plot ordered pairs in all quadrants of a Cartesian plane, and connect the points to create a bat.
Balanced Assessment
Who's Left?
If you're not right-handed, are you wrong-handed? Young statisticians calculate the percentage of left-handed people using a given data set in the assessment task. They plot data on a scatter plot and consider how the line of best fit...
