Math is hard. Or at least, it feels that way when you're six years old and staring at a hundred square that looks like a giant, intimidating grid of secrets. But then someone hits play on a counting in 10s song, and suddenly, the rhythm takes over. It's not about memorization anymore. It's about a beat.
You've probably seen your kid or student bouncing along to a YouTube video where a cartoon penguin or a high-energy teacher shouts out "10, 20, 30!" It looks like simple entertainment. Honestly, though, there is a massive amount of cognitive science happening behind those catchy melodies. Rhythmic skip counting is the bridge between basic addition and the terrifying world of multiplication. Without it, kids often get stuck.
The Neurology of the Counting in 10s Song
Why does music work? Our brains are literally wired to recognize patterns. When a child listens to a counting in 10s song, they aren't just hearing numbers; they are hearing a predictable frequency. Researchers like those at the MIND Institute have long explored how music assists with spatial-temporal reasoning. Basically, the "pulse" of a song mimics the "pulse" of a number line.
Think about the "Big Numbers Song" by KidsTV123 or the various Jack Hartmann versions that dominate elementary classrooms. They don't just say the numbers. They emphasize the "ty" sound—forty, fifty, sixty—which helps kids distinguish these from the "teen" numbers. That's a huge hurdle for early learners. Mishearing "fourteen" for "forty" is a classic mistake that can derail a kid's math confidence for weeks. Music fixes that. It provides a phonetic anchor.
It’s kinda fascinating how a simple melody can bypass the "math anxiety" centers of the brain. When a kid is singing, they aren't worried about being wrong. They’re just keeping the beat.

Why Base-10 Literacy is the Real Goal
We live in a base-10 world. Our currency is base-10. The metric system is base-10. Our very fingers—the original calculators—are base-10. If a child can't fluently count by tens, they are going to struggle with almost every practical application of math later in life.
A good counting in 10s song does more than just list numbers. It builds what educators call "place value intuition." When a child sings "10, 20, 30," they are subconsciously realizing that the digit in the tens place is changing while the zero stays constant. They see the pattern. 1, 2, 3... but with a tail.
Popular Versions That Actually Work
You can’t just pick any random video. Some are too fast. Some have annoying high-pitched voices that make adults want to jump out a window.
- Jack Hartmann’s "Count by 10s": This one is a staple because it incorporates movement. He has kids doing "cross-over" motions, which engages both hemispheres of the brain. It's science disguised as a workout.
- Scratch Garden: This is for the kids who like things a bit weirder and more upbeat. The visuals are quirky, which helps with engagement for neurodivergent learners who might find standard "kiddy" music boring.
- The Singing Walrus: Very chill. If you have a classroom that is already a bit chaotic, this is the one you play to lower the energy while still getting the work done.
The "Hundred Chart" Connection
If you really want to make the counting in 10s song effective, you have to pair it with a visual. Just listening isn't enough for long-term retention.

Visualizing the right-hand column of a 100-chart while the song plays is a game changer. It's about mapping the auditory signal to a physical location. When the singer hits "50," the child's eyes should be halfway down that right column. This creates a mental map. Later, when they have to do 53 + 10, they don't count by ones. They just "jump" down a row in their head. That's the power of skip counting. It turns a 10-step process into a 1-step process.
Common Pitfalls Parents Make
Most parents stop the music too early. They think, "Oh, my kid knows how to count to 100 by tens, we're done."
Nope.
The real test is counting by tens starting from a non-zero number. Can they go 14, 24, 34, 44? A standard counting in 10s song usually won't teach this "off-decade" counting, but it provides the foundation. If they have the rhythm of 10, 20, 30 down, you can start challenging them to apply that same rhythm to other numbers.

Another mistake is ignoring the "backwards" version. Counting down from 100 by tens is arguably more important for subtraction skills. If a kid can sing the song in reverse, they actually understand the relationship between the numbers. They aren't just reciting a poem.
Beyond the Screen: Making it Real
You don't need a tablet to keep the counting in 10s song alive. Use real-world triggers.
- Grocery Store Math: Point out the price tags. "If these apples are 10 cents each, let's sing the song while we bag ten of them."
- Stair Climbing: Every ten steps is a new verse.
- Dime Sorting: Dimes are the physical manifestation of the ten-song. If you have a jar of change, that’s your best teaching tool.
The goal is to move from the song to the concept. Eventually, the music fades away, and the logic remains. But for that first year of kindergarten or first grade, that earworm of a melody is the most powerful tool in the shed.
Actionable Steps for Mastery
To get the most out of these musical tools, don't just treat them as background noise.
- Check for phonetic clarity: Ensure the child is saying "sixty" and not "six-teen." If they struggle, slow the playback speed on YouTube to 0.75x.
- Incorporate tactile feedback: Have the child tap their desk or clap every time they hit a multiple of ten. This physical "bump" reinforces the numerical jump.
- Bridge to 100: Once they master the song to 100, find a version that goes to 1,000. It uses the exact same pattern (110, 120, 130), which proves to the child that math is infinitely predictable.
- The "Stop and Pop" Technique: Pause the counting in 10s song mid-sentence. If the singer stops at 40, the kid has to "pop" out with 50. It tests active listening versus passive absorption.
Mastering the tens column is the single biggest predictor of early math success. It's the "key" that unlocks double-digit addition, multiplication tables, and eventually, decimal places. Keep the music playing until the pattern is a permanent part of their internal monologue.
