*[Update] Here's a video for those visual learners: Vimeo or YouTube.
If you decide to torture your students with the PEMDAS song, here are a few tips:
1. Do a 'call & response.' You start each line of the verse and they finish it:
Students: Start with these
2. Tell your students it will only take a minute to learn and a lifetime to forget!
3. Hire me and I'll come perform at your school. Ha!
4. Don't forget to actually teach them how to simplify/evaluate expressions.
If you're looking for an extension to torturing your students with learning the song, have them rewrite the lyrics of the second verse. Have them write lyrics for the Left to Right rule that applies to Multiplication/Division and Addition/Subtraction. I did this one year and really received some cool lyrics. I also received some terrible ones because those kids could have given a rip about the assignment. Guess what though! They remembered the Left to Right rule. Who's laughing now?
This was a labor of love. I hope you get some mileage out of it, no matter what grade you teach. Lastly, not all your students are the biggest fans of cheesy songs like this. I never was! Hence, my reluctance to record and share. I'm seriously thinking about making a video to accompany the song for those visual learners. Stay tuned!
P.S. Apologies to my Canadian and British readers! PEMDAS is kind of limited to the States. Let me know and maybe I'll upload an instrumental version and you guys can change the lyrics to suit your needs.
