Thank you Tom for the update and the answers to questions.
It seems like the world of competitive soroban is a bit different than what perhaps most of us would be seeking. It’s nice to know the potential is there for really great math abilities.
9th Dan at 6 years old?? Wow.
What does a 6 year old 9th Dan do during math class? I have visions of “ugh… please teacher, can we get to the algebra equations already?”
The mother of the 3 year old is a bit inspirational if not also a bit over the top for what I’d want to do (and probably what most of us around here would want… which says a lot seeing as we’re on a early learning site). I just can’t imagine 4-6 hours of math per day at age 3… or age 20 for that matter :nowink:
However, the point is that she was able to teach her child multiplication and division, and I should point out that the 3 year old handled the pencil quite nimbly. That’s encouraging to know that these things ARE POSSIBLE. The question is how much of the surroundings, influence, practice, importance that’s placed on it, etc is necessary to achieve some level of competency as opposed to mastery where the child enters a competition. I’m not against competition, I’m just not all that interested in it unless my child really loves to compete and it’s a motivating device. Most people don’t think of 3 year olds as competitive, but maybe I’m wrong about that [feel free to correct me everyone]
I also want to point out to everyone reading this thread that the older sibling in the video was doing the multiplication without using the abacus. It sat to the side as she worked through the problems mentally (you can see her using her fingers as she mentally works with the image in her mind), and we’re not talking about basic multiplication here (such as 6x8); I’m pretty sure this was multi-digit multiplication. Maybe Tom can give us an example of a multiplication or division problem these kids were working through.
Tom, how much technique is necessary for success? You mentioned the video that talks about the flick… is it important to spend time initially learning the basic finger movements for optimized speed, or do you just jump in and start using the beads and worry about technique later?
Along those lines, I’ve wanted to know what sort of “warm up” drills the kids do. In some videos I’ve seen, the teacher instructs or talks about doing a drill or drills, but no one has ever put a drill on youtube or written down a drill. These kids would work through their drills to build speed. Perhaps you can give us an idea if there are drills that can be done, and what these would look like?
I’ve seen 10th Dan on youtube doing mind shattering math problems… but what’s the difference between 1st, 2nd, 3rd… 9th, 10th Dan? Is it speed, accuracy, complexity, or a combination of these? If complexity plays a role, I’d be curious to see a problem that a 1st Dan can solve vs a 10th Dan… that would give us an idea of the capability of the abacus.
As for instruction; is there a way to break it down into step by step? Obviously everyone understands different concepts at different stages, but is there a basic outline? If it’s not linear, then perhaps there are just “stages” that should be kept in mind??
Do you like using a soroban with the clearing mechanism? is one advised for kids, or just use a classic one that does not have it? Mine doesn’t have it, and it’s a pain to clear the darn thing and sometimes the beads move whenever I have to move the soroban from one spot to another, which then requires that I clear it out again (wasting time)
Thanks again! (hopefully my questions help you with your videos)
