Did you know that scientists now agree that there was a dinosaur called the Brontosaurus? Does that have anything to do with multiplying fractions? You'll have to watch this video to find out. This song's got a catchy chorus and some pretty clever lyrics that will capture the attention of every student in your class.
Multiplying Fractions Song Lyrics:
Three of us found treasure on a scuba trip,
So we pulled our treasure onto the ship.
Since we were so blessed by this rarity,
We decided to give half of it to charity.
We took the rest and split it up three ways;
One third of the rest was still a huge payday!
One third for me, one half for charity,
So what’s my share? Let’s multiply and see...
When we need to multiply two fractions,
This is our reaction:
Multiply the numerators,
Then multiply the denominators.
My friend and I were digging for dinosaur bones.
We decided to search in a rectangular zone;
We split up equally between the two of us.
The first day I found a bone from a brontosaurus!
I found a few more by the end of day two,
When three eighths of my half had been searched through.
Of my half, I had explored three eighths;
how much of the entire space did I excavate?
If you are interested in getting ideas on how to plan a robust standards-aligned Multiplying Fractions lesson, we recommend checking out Instructure's recommendations for common core standards 4.NF.4, and 5.NF.4 . These pages help break down standard language, lay out the grade-appropriate level of rigor for each concept, and offer a variety of suggestions for activities (lesson seeds) that help students achieve their learning targets.
