I couldn't hope to determine if the early training had anything to do with it or just the overall attention to early education, but I will say that she developed an affinity for math at a young age and even in preschool tended to be interested in the more advanced concepts of abstract math rather than simple counting of objects.

I did teach both my children to count on their fingers using the pattern taught by ASL. I've noticed that sometimes her friends look at her oddly when she holds up her index, middle, and thumb for the number three, and obviously, they have no clue that holding up the index, middle, and ring fingers might mean either six or three to her depending on to whom she is talking.

I introduced both my children to an awesome game when they were just in kindergarten: http://www.dragonboxapp.com/ it teaches basic algebraic concepts cloaked in the guise of a fun puzzle game.

I find the finger counting (3 with thumb, index, and middle finger) interesting. Here in Asia that could mean 8.

I was first taught to count starting from the index finger as well:

fist = 0

index = 1

index, middle = 2

index, middle, ring = 3

index, middle, ring, pinky = 4

index, middle, ring, pinky, thumb = 5

thumb = 6

thumb, index = 7

thumb, index, middle = 8

thumb, index, middle, ring = 9

(I am from Thailand, but I think this is how counting is taught in America as well?)

I thought this was universal until I went to Singapore. I was quite intrigued that in Singapore a "thumb" is not considered a number but rather a signal for "good" and instead they used thumb + pinky for 6. (The rest seems to be the same.)

Not sure why I brought that up, but I guess I had not realized that there was a difference in even the way we counted all around the world until that point.

EDIT: Formatting

Typically, kids in the USA are taught 1 - 5 the way you describe, but not taught anything further with a single hand. If they want to count to ten, they use both hands in the same manner.

There are a few other fancy ways including even binary which could let you count up to 1024 if you could keep it all in your head. :)

The ASL (American Sign Language) method I mentioned in the parent is described here: http://www.dummies.com/how-to/content/counting-on-numbers-in...

I annoyed my teachers in elementary school demonstrating binary finger counting to 1024 when they were insisting that students stop finger counting because "you could only count to 10"

I was a precocious little shit.

Yeah, my dad taught me to count on my hands in binary when I was young. I tried explaining it to others but that usually broke down when I reached four...

I taught my daughter starting with fist, so zero was natural.

Then, when we started playing board games there was an issue playing games like "Game of Goose" because she started counting with 1 in the occupied space. We "fixed" that starting with 0.

My hand cannot do 9 the way you describe. My pinky is too stubborn.

It sounds like (unsurprisingly) Singapore uses the same system used here in Hong Kong. I'm not sure if the same system is used in mainland China.

fist = 0 index = 1 index, middle = 2 index, middle, ring = 3 index, middle, ring, pinky = 4 index, middle, ring, pinky, thumb splayed = 5 thumb, pinky = 6 index, middle, ring, pinky, thumb all held strait with their pads touching, looking a bit like a shadow puppet of a bird's head = 7 thumb, index = 8 just the index finger, bent in half = 9

Yes, the same system is used in mainland China.

Apart from 4 and 5, you can kind of see the link between the written form of the number and the hand signal: 1, 2, 3: obvious because 一二三 6: the thumb and pinky make up the bottom part of the character 六 7: If you look at your own right hand upside-down when making the gesture, the bird's head points in the same direction as the 七 8: Your thumb and index finger are the two lines in 八 9: Your index finger is the second stroke in 九

I don't know whether this is coincidental, or even just my imagination...

> I've noticed that sometimes her friends look at her oddly when she holds up her index, middle, and thumb for the number three,

Hmm interesting. I have been trying something different as well. I have been counting with fingers with my kid using different fingers every time. The idea is that it doesn't matter to associate a finger with a number as long as the correct number of fingers is up. Like say most people start with the thumb and move left or right. Sometimes I start with the ring finger.

Counting is also fun in general. We count steps, count trees when we drive. I try to never make it about teaching but more about fun.

Thanks for the link, the game seems awesome !!
