This started as my 180 blog. Then life got busy. Now it's a combination of One Good Thing and #Teach180
I can't see the index cards clearly. Is there a scatterplot on one side and the description in context on the other? How many different cards did you need and for how many students?
I used 16 different cards. One side had a scatterplot, the other side had a description in context. I printed 2 sets of the cards. The inside circle had one color, the outside circle had the other color.
