A former student met me in the hallway today. She heard we had just learned the quadratic formula in algebra 2, and she took it upon herself to choreograph a dance to go with the song I teach. With illustrations.
She offered to come to class and perform it for my current students . . .
. . . but only if I joined in, which I did. Except for the slap the butt part.
Sometimes, high school students are just adorable.
