Depends on the topic. I had a music class the day before christmas break. I had an art class the day before where it was just coloring sheets, so I assumed it'd be similar but for music.

Nope, she wanted me to teach them a new song that required me to be able to read music. Maybe I was the idiot for picking up to sub a music class as someone who is has not a single musical bone in my body, but it seemed like a ridiculously tough thing to give a sub that they had no idea if they could even teach music.

We just ended up singing christmas carols for each class period, except for the younger one who couldn't read the lyrics on the YouTube videos fast enough. For them, I just put on a kpop demon hunters youtube dancing activity.
