If you’ve ever tried to order two coffees in a loud room or shout your phone number across a crowded bar, you already know the frustration of "visual communication" failing. But for the Deaf community, numbers aren't just a backup; they're a foundational part of American Sign Language that most beginners actually mess up within the first five seconds. Seriously. Most people think they can just hold up a hand and count like they did in kindergarten.
They can’t.
Learning ASL numbers 1-20 is less about memorizing digits and more about mastering palm orientation and subtle wrist flicks. If your palm is facing the wrong way, you aren't saying "two." You're just gesturing. It's the difference between speaking a language and just making noise with your mouth.
The Palm Orientation Trap
Here is the thing that trips up literally every new signer. For the numbers 1 through 5, your palm stays facing you. Not the person you’re talking to. If you hold up an index finger with your palm facing the world, you’re not signing "one" in ASL; you’re just pointing or indicating the number in a "hearing" way.
Why does this matter? It’s about clarity and linguistic history.
When you hit 6, everything flips. Suddenly, your palm faces out toward the observer. It feels counterintuitive at first. You've spent years showing people "three" by holding up three fingers with your palm out. In ASL, if your palm is out for numbers 1-5, you’re usually indicating a sequence or an address, not the cardinal number itself.
- 1 through 5: Palm faces the signer (inward).
- 6 through 9: Palm faces the listener (outward).
Honestly, the "3" is the biggest hurdle. Most English speakers use their index, middle, and ring fingers. In ASL? That’s wrong. You use your thumb, index, and middle finger. It looks like a little "W" or a finger gun with an extra barrel. If you use your ring finger for "3," a Deaf person will still understand you, but you’ll have a massive "accent" that screams you just started yesterday.

Why 6 Through 9 Feel Like a Secret Code
Once you hit 6, you start using your thumb to touch your other fingers. It’s a tactile system.
Think of it as a countdown on your own hand. Your thumb touches your pinky for 6. It moves to the ring finger for 7, the middle for 8, and the index for 9. A common mistake is thinking the "smallest" finger (the pinky) should be the smallest number (1), but ASL logic doesn't work that way. The pinky represents 6 because it’s the "first" stop on the thumb’s journey across the hand.
Bill Vicars, a legendary figure in ASL education and founder of Lifeprint, often emphasizes that these movements need to be crisp. If your thumb is just hanging out in the middle of your palm, "8" starts looking like "7" or a weirdly collapsed "9." Precision is everything when you're signing in a dark restaurant or from ten feet away.
Then there is 10. It’s just a "thumbs up" with a little shake. Simple, right? But don't over-shake it. It's a wrist wiggle, not a thumb-wrestling match.
The "Teen" Numbers Are Where It Gets Weird
If you thought 1-10 was tricky, the 11-15 range is where people usually give up and go back to pointing. These aren't static signs. They involve "flicking" or "jumping."
Take 11 and 12. You keep your palm facing you. For 11, you flick your index finger up twice against your thumb. For 12, you do it with both the index and middle fingers. It’s like they’re trying to escape your hand.
13, 14, and 15 change the game again. You tuck your thumb in (except for 15, where it stays out) and "wave" your fingers toward yourself. It’s a beckoning motion. If you do this with your palm facing out, you’re basically just waving hello to someone in a very confusing way.
Then, at 16, we see the "twist."
The 16-19 Variations
There are actually two main ways people sign 16 through 19, and it usually depends on where they learned or how fast they’re talking.
- The Twist: You sign the base number (like 6) and twist your wrist back and forth.
- The Rub: You rub the thumb against the finger (like the 6, 7, 8, or 9 position) repeatedly.
Most classrooms teach the twist. However, in the "wild"—meaning the actual Deaf community—you'll see a lot of variation. It’s like how some people say "can’t" and some say "cain’t." Both are 100% understood.
Finally, 20. It looks like a little bird beak. Your thumb and index finger tap together. It’s arguably the most satisfying sign in the first twenty numbers.
Beyond Just Fingerspelling
Numbers in ASL aren't just for counting apples. They change based on what you’re talking about. This is where "Numerical Incorporation" kicks in. If you’re talking about time, or age, or money, the sign for the number might actually blend into another sign.
For example, when signing age, you don't sign "I am" then "age" then "five." You touch your chin (the sign for age) and pull the number 5 out directly from there. It’s one fluid motion. If you don't know the basic ASL numbers 1-20, you can't even begin to grasp these compound signs.
The Cultural Impact of Getting It Right
Using the correct "3" (thumb out) isn't just about being a perfectionist. It's about respect.
The Deaf community has a long history of being forced to adapt to "hearing" ways of communicating. When a hearing person takes the time to learn the specific linguistic nuances of ASL—like the palm orientation for 1-5—it signals that they view ASL as a legitimate, sophisticated language, not just a collection of gestures.
It’s also about safety and accuracy. In medical settings or emergency situations, mistaking an 11 for a 1 or an 8 for a 7 because of poor palm placement can have real-world consequences. This isn't just a hobby; it’s a tool for connection.
How to Actually Retain This
Don't just watch a video and think you've got it. Your brain will lie to you.
The "sinews" of your hand need to build the muscle memory. Try signing your phone number. Then try signing the prices of things you see at the grocery store. If you see a cereal box for $4.99, sign the 4 (palm in!) and then the 9 (palm out!).
Consistency beats intensity every time. Signing for five minutes a day while you’re stuck in traffic (one-handed, obviously) will do more for your fluency than a three-hour cram session once a month.
Common Mistakes Checklist
- The "Palm Out" Blunder: Keep palms in for 1-5.
- The "Hearing 3": Use your thumb, not your ring finger.
- The "Lazy 10": Make sure the thumb is extended, not tucked.
- The "Static 11": Remember to flick the finger twice.
Learning the numbers is the gateway. Once you can comfortably navigate ASL numbers 1-20, the rest of the numbering system (which goes up to the millions and beyond) follows a surprisingly logical pattern. But you have to get the foundation right first.
Start practicing with your non-dominant hand too. While most people sign with their "right" (or dominant) hand, being able to understand numbers coming from either side is what separates the students from the fluent signers. Keep your wrist loose. Keep your palm facing the right way.
Next time you’re at a bar and it’s too loud to hear your friend, try signing how many drinks you want. Just make sure that for those first two beers, your palm is facing you.
Your Next Steps for Mastery
To move from "memorizing" to "using," you need to break the visual-to-English translation loop in your head. Stop thinking of the word "twelve" and then the sign. Instead, look at a group of twelve objects and immediately produce the double-flick sign.
Practice these three drills this week:
- The License Plate Game: Sign the numbers of every car you see while walking.
- The Countdown: Sign 20 down to 1 as fast as possible without losing palm orientation.
- The Age Pull: Practice touching your chin and pulling out numbers 1-20 to simulate telling someone's age.
Once your hand stops cramping during the transition from 5 to 6, you'll know the muscle memory is finally sticking.
