As an introduction to Even/Odd functions, I gave out these six graphs on paper and asked them to classify them into three equal groups by using the word “Symmetry”. Really cool to see the different and correct answers that the groups gave. Some groups categorized them into the intended even/odd/neither symmetry groups, others had different but correct arrangements. Fun < 5 min intro.

Also this desmos activity worked nicely for students as a connection between the roots of a polynomial to the factors to the multiplicities of the factors.
