Hello! I have been editing this awesome activity. I would like to have students create an estimated line of best fit by dragging the points, then identify their created line’s slope and y -intercept values for correctness. Thanks!
This is such a cool activity! Are you looking to have the activity check whether the student’s calculated slope/y-intercept for their line is correct based on the line they drew, or based on the actual best-fit line?
Thanks Andrew! I am looking to have the activity check whether the students calculated slope and y-int for their line is correct based off of the line they drew. I plan to build on that and have them compare it to the actual line of best fit once they have found it. I have not yet made all of those slides if you have any suggestions or tips too.
Hey Nina, I put some images together to hopefully help.
On Screen 1, I noticed you have “slope” in line 13, I pulled this out to be its own variable (line 14), which then you can pull and compare against the students input on screen 2.
I did the same for the y-intercept on screen 3, I added lines 15-16, which you can pull and compare against the students input. Want to note that if the slope is say 2/3, this does not take in account any rounding.
