Godzilla goes underwater in this video to chase submarines which are affixed with fractions that display simplified fractions and their unsimplified pair. Meanwhile, on land, numbers are being catapulted into the skyline where they fall down as parts of a fraction in its lowest term. Your students will love this cute little video about simplifying fractions!

"Simplest Form / Simplifying Fractions Song"


To convert two-fourths to simplest form:
write out all the factors of two and four.
The greatest common factor is two,
so divide them both by two.
Two-fourths equals one-half, and here’s what we do...


To convert to the simplest form,
we’ve gotta find the greatest common factor.
Then take that numerator and denominator
and divide them by that common factor.

To convert four-twelfths to simplest form:
Write out all the factors of twelve and four.
Four is the greatest common factor
So divide by four-fourths to see...
Four-twelfths equals one out of three.


“Simplest form” and “lowest terms” are synonyms
- which you may have heard are two different phrases or words
whose definitions are uniform.
Using a geometric model can help us learn
what’s happening when converting to simplest form.

A rectangle shows five-fifteenths - (so the) The GCF is 5,
which means no greater number can divide both fifteen and five.
So divide both by five; get one-third, its lowest terms.

It’s so boss being a nerd!!


»»-------------¤-------------««»»-------------¤-------------«« is a provider of educational videos for kids which was founded by an innovative 5th Grade teacher who envisioned a new kind of classroom where students got energized for math class. Parents of his students even noticed their children singing mathematics songs around the dinner table well beyond school hours.

Seeing his students so enthusiastic when it was time for math was welcome, to say the least! But the epiphanous moment was when students were singing math songs all-day long like they were in the American Top 40!

Each of these rhythmic musical math videos from NUMBEROCK can be enjoyed right here on our YouTube Channel. We, hereby, cordially invite you to browse through the full library and hope you'll find that the songs make the maths* remarkably more fun.

We dare to believe that these math songs + videos can actually identify with elementary school children's increasingly finicky perception of what is cool and trendy. While each song is diverse in composition, most fit directly into the modern musical genres that excite young kids: genres such as Rap, R&B, Pop, Hip-Hop and even Reggae!

We're curious to see how these musical math videos will be used now that we have shared them with a broader audience. But whether you use these songs as a rich teaching resource or just to brighten up the school-day a bit, we hope that as our project continues you will eventually find a relevant song for each lesson plan and concept in the math curriculum taught throughout the academic year.

Our main goal is to make teaching and learning math more fun and more interactive. SchoolHouse Rock! has done this in other subjects for us in the previous generations, and many of us still enjoy watching their YouTube Videos which teach us about Government, Science, and English amongst other subjects.
Flocabulary is another company which is doing something similar at the moment – and we wish them all the best!
