How easy/hard was it to for y'all to learn your multiplication tables? What grade did start learning and when did you know it all? (up to 12x12 I mean)
-
So for context, I went to first grade in mainland China before immigrating to the United States, in China, they teach kids this weird trick that's basically like reciting a "poem" thing, which I didn't remember what it was called until I recently googled it. Its apparantly called the "九九乘法口诀表" or 9x9 Song / "The Nine-nine song" (Wikipedia article: https://en.wikipedia.org/wiki/Chinese_multiplication_table#The_Nine-nine_song_text_in_Chinese).
So like... in 2nd grade, for which I was in the US, multiplication was very easy for me, well... at least up to 10x10. Like idk how to explain it to someone who's doesn't speak a variant of Chinese, and even the rhythm only works for me in Mandarin somehow, when I try to use Cantonese, which is the language I speak at home in the US, I cannot replicate the rhythm to make thay thing work, this "Poem"/"Song" is only available to me in Mandarin, like when I think about multiplying together any 2 single digit number, I instictively use the "九九乘法口诀表".
Like its goes from 1x1 then next lines are 1x2, 2x2, then next are 1x3, 2x3, 3x3, then its 1x4, 2x4, 3x4, 4x4, etc... you get the idea, mutiples of 1, then 2, then 3. So if I need to multiply something by 7, I can start from the line where multiples of 7 are. Sometimes I can remember the exact phrase of it like for example 3x7, without starting from 1x7, then 2x7, then 3x7.
Like I never thought too hard about it, it kinda just became the "normal" way I do multiplication. But someone asked a question on Lemmy about reading analog clocks and I probably didn't answer their question correctly but that was when I kinda was like: oh wow I forgot that my way of multiplication is probably different from everyone else in the west.
Like if you told me to teach a English-Only speaker on how to do multiplication tables, I... um... I don't know how I would teach that, the "九九乘法口诀表" doesn't have the rhythm in English so I doubt converting the it to English would work.
Like even though I speak English as my primary language now, and I barely have any fluency in Mandarin or even Cantonese which I speak at home (and never learned any vocabulary beyond the basics), the "九九乘法口诀表" multiplication thing is always done in mandarin somehow, like its always been stuck in my brain even after all these years in the US.
TLDR answer to my own question. I do it using "九九乘法口诀表" which takes me 1-2 seconds to recall a specific line, so basically, anything up to 10x10 takes about 2 seconds for my brsin to process, 11x11x to 12x12 takes about 5-10 seconds, anything bigger and I just giveup using my brain and pull out a calculator. I memorized 10x10 since first grade, then 12x12 probably by like 2nd grade or maybe first half of 3rd grade.
How do y'all do it, is it easy or hard?
Edit: Okay so the best way for me to explain "九九乘法口诀表" is that: Think of PEMDAS (order of operations), but its for the entire multiplication up to 9x9.
wrote last edited by [email protected]I learned multiplication by flash cards in kindergarten and first grade, but I think they generally teach multiplication tables in third grade. I never really learned them because am very bad at memorizing. I just faked it since I could calculate it in my head fast enough (although I was always much slower than my classmates).
Gifted education is a scam.

In the UK we also had a song thing for the first 12 times tables, but I was never good at rhythmic recall as a kid so I always had some issues with 7 and 8 times tables.
Was pretty good at all the rest by the start of Year 3, though.

I never learned it. We had specific tests just for them i 3rd grade and I just could never be bothered to actually learn them. I just did the calculations every time and even with the really short time limit I could get over 90% right. So I thought why bother.

Never bothered to learn them. Learned to compute rather than memorize, based on numerical relationships. Ex: 73 * 13 = 75 * 13 - 2 * 13 = 975 - 26 = 949.

I think we had up to do up to 12 times tables by 3rd or 4th grade. I remember starting in 1st at school but really I learned them from Schoolhouse Rock. In the states Schoolhouse Rock was on Saturday Mornings between regular cartoons and they had such great songs.

We briefly touched it in primary school in Australia, but ROTE isn’t really learning anything so it wasn’t a big emphasis.
-
In US, in 1st/2nd we did phonetic learning of the times tables 12x12 as well as the states in alphabetical order and the president's in order of inauguration.
still easy to recite today.
the states in alphabetical order and the president’s in order of inauguration.
Lol I only know like 10 president's name before it was too much depressing history for me. They never tested us on it. They made us fill in state names with a blank US map and the capital of each, I think I got like a 70/100 on the test, didn't like it. Idk why learning 50 US states is gonna help me since I'm not going to like half of them cuz um... ahem politics

We stopped at ten and I've never learned them due to it being, in my opinion at the time, waste of time as you can always just count. They are pretty useful actually.

I remember before I move to the US, in China, they tried to make kids memorize a whole story (some children's story I think, forgot what that was about) and kept kids after school if they didn't memorize it (like a "detension" basically).
In the US, I had to memorize the Preamble of the US Constitution, I promptly forgot it after the test lol. (I mean considering current US political climate, that went out the window so it doesn't even matter anymore lol)
But the "九九乘法口诀表" stuck around with me somehow, sometime rote memorization do work, sometimes.

I don't remember if it was 2nd or 3rd grade, but I just memorized them. My grandmother bought flash cards and drilled them with me every day until I had memorized them all.

ROTE can help you memorise stuff, but it’s like trying to memorise the shape of every word instead of learning how to read the letters.
Better use of time was learning how to multiply and be able to work out any number.

Sometimes I can remember the exact phrase of it like for example 3x7, without starting from 1x7, then 2x7, then 3x7.
Like I never thought too hard about it, it kinda just became the "normal" way I do multiplication. But someone asked a question on Lemmy about reading analog clocks and I probably didn't answer their question correctly but that was when I kinda was like: oh wow I forgot that my way of multiplication is probably different from everyone else in the west.
Like if you told me to teach a English-Only speaker on how to do multiplication tables, I... um... I don't know how I would teach that, the "九九乘法口诀表" doesn't have the rhythm in English so I doubt converting the it to English would work.
Like even though I speak English as my primary language now, and I barely have any fluency in Mandarin or even Cantonese which I speak at home (and never learned any vocabulary beyond the basics), the "九九乘法口诀表" multiplication thing is always done in mandarin somehow, like its always been stuck in my brain even after all these years in the US.
TLDR answer to my own question. I do it using "九九乘法口诀表" which takes me 1-2 seconds to recall a specific line, so basically, anything up to 10x10 takes about 2 seconds for my brsin to process, 11x11x to 12x12 takes about 5-10 seconds, anything bigger and I just giveup using my brain and pull out a calculator. I memorized 10x10 since first grade, then 12x12 probably by like 2nd grade or maybe first half of 3rd grade.
How do y'all do it, is it easy or hard?
Edit: Okay so the best way for me to explain "九九乘法口诀表" is that: Think of PEMDAS (order of operations), but its for the entire multiplication up to 9x9.
Still dont know em. Did advanced math and now 90% completed an engineering degree. Their is no point to memorising them in this day and age.

So for context, I went to first grade in mainland China before immigrating to the United States, in China, they teach kids this weird trick that's basically like reciting a "poem" thing, which I didn't remember what it was called until I recently googled it. Its apparantly called the "九九乘法口诀表" or 9x9 Song / "The Nine-nine song" (Wikipedia article: https://en.wikipedia.org/wiki/Chinese_multiplication_table#The_Nine-nine_song_text_in_Chinese).
So like... in 2nd grade, for which I was in the US, multiplication was very easy for me, well... at least up to 10x10. Like idk how to explain it to someone who's doesn't speak a variant of Chinese, and even the rhythm only works for me in Mandarin somehow, when I try to use Cantonese, which is the language I speak at home in the US, I cannot replicate the rhythm to make thay thing work, this "Poem"/"Song" is only available to me in Mandarin, like when I think about multiplying together any 2 single digit number, I instictively use the "九九乘法口诀表".

Much easier when I learned you just take the previous number and add + whatever to it.
5 X 8 = 40
5 X 9 = 45 (40+5)
5 X 10 = 50 (45+5)
5 X 11 = 55 (50+5)

wrote last edited by [email protected]Never really memorized it. I just calculated it in my head, unless I had a calculator accessible. It’s slow, but gets the job done.
I got quite fluent in matrix multiplication for a while during my university years. That’s what linear algebra and no calculator exams does to one.

We converted everything to and from base 60 (sexigesimal)

If i remember, the way I was taught was by doing basic single digit multiplication in many different contexts so much that I slowly internalized the math. There were multiplication tables we filled out in class, multiplication videogames, multiplication flash cards, multiplication board games, multiplication storybooks, multiplication puzzles, multiplication games in PE.
And I was primed for learning division in preschool through the concept of sharing. If you have 18 cupcakes and eight friends, how many should your friends and yourself get? If you have a pizza with 12 slices and four friends, how do you share fairly? If you think about it, that's the multiplication table they were teaching me there, just slower and backwards.
-
I also just work it out in my head. There are certain "landmark" numbers and tricks that I use to save time. For example, 9 times any number is easy: multiply by 10 and subtract once. x11 is similar. Same with anything close to a perfect square. (7 x 8 = 7 x 7 + 7)
I think that memorization was important to achieve speed before phones/calculators. Nowadays, I would consider memorization an obstacle to understanding.
As a teacher, no, memorization is an important step before understanding. I do agree thought that in the times before memorization was a bigger emphasis, but that's because it was understood that the only information you'd have easy access to would be what youve memorized since we didnt have the internet. Now we teach kids in Literature class how to vet their sources because they are all exposed to the misinformation vortex.

wrote last edited by [email protected]I memorized the easy stuff and would just add or subtract to get to the right answer (because multiplication is just repeated addition). So 6*7 is just 6*6+6=36+6=42. It was pretty easy for me because the multiplication table is choke-full of patterns like multiples of 2, 5, 9 and 10.
