# It’s All in the Surface

An engaging rap song for teaching surface area formulas to students. Includes fun worksheets and multiple versions of the song to assist with scaffolding.

This song teaches different formulas for the surface area of geometric figures. The song instructs students on how to find the surface area of sphere, cube, box, and cylinder while explaining the meaning of each variable in the different formulas. There are teaching materials, including worksheets, activities and games, which are resources for teachers and homeschool parents to create lesson plans for the song topic. With the help of "Its All in the Surface" students will have a better understanding of how to calculate surface area of geometric figures.

This math song is suitable for teaching formulas to elementary school (4th grade, 5th grade and 6th grade, middle school, high school, and homeschool students as well as beginning college classes.
Verse I
You’ll hear it straight from me, so have no fear
r represents the radius, you know
Take 4 × πr², then you’re good to go
Got that, let’s move on to the cube
6 × a² is what you gotta do
a is the length of the side of each edge

Chorus
It’s all in the surface, so take a ride
‘Round the top and the bottom and around the sides
We inform with a purpose, the formulas for surface
Yeah, that’s the area we’re gonna describe
(×2)

Verse II
Stay with me, it’s gonna get tricky
When you’re dealing with a box it’s a little more iffy
a, b, and c are the lengths of three sides
With different combinations, just multiply
2 × a × b, add it to the 2 × b × c,
and add it to the 2 × c × a
Now you’re dealing with the surface of a box (OK!)

Chorus

Verse III
The surface of a cylinder may take a little time
It’s the top and bottom plus around the side
If it helps think of a Coca-Cola® can
So you can make more sense of the formula at hand

2 × πr² added with the 2 × πrh
h is the height, all right? That’s it, you see
The cylinder’s surface is a breeze

Math Is Fun
