I really don’t know how people taught before the internet. Luckily, I don’t have to! I found some beautiful “end behavior” cards on the amazing Amy Gruen’s blog, “Square Root of Negative One Teach Math“. I doubled the set, adding the number of roots (real and imaginary), as well as direction and wanted to share them back out.
I passed them out to review end behavior and roots, but I wish I would have had these as a discovery lesson to introduce the concepts.
The amazing Amy is some sort of card sort savant. I also saw a Desmos card sort that I can’t wait to explore.
