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.

  • I memorized them. 'I didn't feel like it' was not an option. We did times tables every morning, everyone knew them after a while.

  • 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.

  • My dad played a kind of patty-cake growing up where I practiced doing times tables in rhythm. My dad would pick the addend and set the pace, and we'd alternate left and right hand high fives while saying say multiples of four. 4 8 12 … 36 40, then we'd just switch to 7's, slightly slower pacing 7 14 20~ … if i made mistakes - 21, let's try again: 7 14 21 2…8 35 … no reprimand for error - we had a beat to keep, just take a downbeat and try again. Of course simpler numbers were taken further 3s were occasionally done out to 300, and 2s were done as fast as I could spit out the words. 5s were often the rest set, done at a basic pace.

    The madlad had me polishing my 13×13s before school ever even mentioned the existence of multiplication.

  • Only did it to 10x10 in my country :3

    It was like.. 2nd or 3rd grade? Anyhow, Im still bad at them, but that's cause my brain does numbers weird lol

  • 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 👀

  • I did it in Cantonese, probably similar to the Mandarin poem.

    I think my mom started making me memorize it in the last year of kindergarten (I was 5yo). By the time multiplication becomes the main topic in primary 2 (2nd grade) maths, I didn't really have much problem doing them. It was really useful to have it recited.

  • I grew up in Quebec until I was 7, and then moved to Ontario half way through the school year for Grade 2.

    In Wakefield we were just starting to learn the times tables. In Ottawa, they were finished with them and were just about done division. I never really got to learn either before learning fractions.

    As a result, while i can do quadratic equations and fractions in my head, I often struggle to reason out multiplication or division.

  • One of the very few teachers I remember (I’m 68) was Fred Ross due to how effectively he taught me the times tables and more. That guy for months on end drilled the times tables into our heads by repetition. There were no calculators or internet then so it was the most effective way and it worked too.

    He also posed a question that to this day I have not found the answer. An English only word with the letter q in it but no u after the q. Can only be a regular word not a name or a city.

  • I was only taught up to 10×10 in primary school, and learned mostly by rote (and also, "skip counting"). I've also heard of some techniques like matching fingers to do one-digit multiplication, but I never really learned how to do that. By that point, I've mostly memorized the multiplication table up to 10.

    For 11, it's absurdly easy once I got the technique, just double the number (up until 9). 11×10 is just appending a zero, and 11×11 I just memorized.

    For 12, I actually didn't bother that much? 12×N = 10×N + 2×N. Thus, 12×11 = 110 + 24 = 134 and 12×12 = 120 + 24 = 144 (which I got memorized for some reason).

    I still have some trouble with the 6, 7, and sometimes 8 multiplication tables, but I can usually recall it with a bit of effort. Not much, but not without some awkward pause.

    Now, for how I got to memorize it. The process was hard at first. I had to recite the multiplication tables as a drill almost everyday. We also had long quizzes (hundred items) of one-digit multiplication and two-digit division (by the fourth grade), so there's an incentive to memorize the tables if only to be able to get through those quizzes with minimal pain. There's also a social stigma for being the last person to get done with those quizzes (or worse, running out of time), so there's that pressure too.

  • 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.

  • 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.

  • I struggled learning them but that was in part due to me not wanting to learn them. I got by, barely. Currently, I'm pretty good with some of them but no expert.

  • I learned up through 12 x 12 in 2nd grade. Some of them were easier than others. I remember drilling with my grandfather for hours to memorize the ones I was having trouble with. The incentive was that if I learned them, he'd buy me a GameBoy game I wanted. I did in fact get the game when I managed to master multiplication—it was Mole Mania, a sokoban-style puzzle game with the gimmick that there is an underground layer you can move through that also has its own obstacles.

  • Memorized in 6th grade. An optional goal in class to complete the “60 second sweep”. It only went up to 9, but we had to get in front of the class and do them all in 60 seconds.

  • We briefly touched it in primary school in Australia, but ROTE isn’t really learning anything so it wasn’t a big emphasis.

    • 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.

      • 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.
