This is a pack of two short songs (just the chorus) about how to round to the tune of "Price Tag" by Jessie J and how to simplify expressions to the tune of "Holy Grail" by Jay-Z featuring Justin Timberlake. My students and I sing this multiple times throughout the year to compute with decimals. I also use it as a call and response when students get stuck and don't know what to do. I'll watch students mouthing the words on tests and quizzes to help them remember. I've also gotten public performances when I've run into students outside of school.
To use in your classroom search on YouTube or download an instrumental version of each song. Copy the song lyrics for students to see easily. Sing along to the instrumental. I have my students stand up and they come up with fun dance moves that help us remember what to do. Have fun singing and solving with your students!
Also available as part of a pack in Math Songs Pack 2.
