Japanese abacus math8/16/2023 I took abacus classes when I lived in Japan for several years as a child. The problem can be solved arithmetically and algebraically, and the merchant solves it arithmetically, cannot do a system of equations with abacus. This is a fun short story by Chekhov about a high-school tutor failing to solve a middle-school problem that the merchant father of the middle-schooler solves in seconds using abacus (called counting board in this translation). I think if you just explain how addition and subtraction works, that would be good enough return for your \$10. Division requires some mental math, which itself can be a good reason to refresh multiplication table and division shortcuts. This abacus is much closer representation of decimal system than soroban - one wire is one decimal place.Īdding and subtracting is simple. Ten beads on a wire may seem excessive - you need only nine - but come handy when you want to break a higher-place value into lower one, like breaking one thousand into ten hundreds. The wires are not curved, and the colors are just for fun not for easier grouping, but it is good enough to teach decimal system and place value. It has horizontal wires with ten beads on each, which is similar to Russian-style abacus. Some sell \$1B worth of iPads, other sell abaci.ĭo your school budget a favor and get an abacus at Ikea for \$10. "The companies that run these expensive programs" just want to make money. International Journal of Research in Education and Science (IJRES), 2(1), 172-178. The teachers' views on Soroban abacus training. The conclusions section of the article refers to other studies that might be of interest in answering the question. This method can not distinguish between mathematically gifted students taking abacus classes and between students taking abacus classes becoming better.įurthermore, one would expect any engagement with mathematics to lead to improvement, so a pertinent question is if this method leads to more improvement than other activities. The method used was asking teachers if the students taking abacus classes are doing better than others. I checked the Finnish publication forum, which has rated the journal as scientific but not exceptionally good since 2017. I do not know the landscape of education journals well enough to know if the journal is of high quality. The article, according to the abstract, (, )
