Abacus Mental Math in Asia and the West
January 27th, 2008 · No Comments
For years and years in America, Chinese and Indian engineers and doctors have marveled their fields. We see them in every high-tech firm and hospital. Quite a few of you wonder how come there are so many Chinese and Indian engineers. How come there are so many Indian doctors and nurses?
Every time we visit our children’s schools we see Chinese and Indian students marveling at SATs. And we all know why they succeed in Engineering and Medical fields. Answer is quite simple, they are good at Math. But why are they so good? How did they study Math that makes them so good at that one arduous subject? What do these Asians (Chinese, Japanese, Indians, etc.) do to make their children so good with Mathematics? Answer is quite simple, practice, practice & practice. But what is it that those students actually practice? The answer is Abacus Mental Math!
Lately, Abacus mental math has taken some of these Asian nations by storm. Abacus is a Latin word that has its origins in the Greek words abax or abakon (meaning “table” or “tablet”) which in turn, possibly originated from the Semitic word abq, meaning “sand”. The abacus is an instrument, a manual tool invented by the Chinese 2000 years ago.
After years and years of research, Abacus has made a come back. Today if you visit Malaysia, Taiwan or India, you might find training center pretty much at every corner focusing on just one subject - abacus math. Over the past five years, in nations like Malaysia, Taiwan and India, countless tutoring centers have sprung up with one goal in mind, tutor abacus mental math. Most of these centers offer training using the Japanese “Soroban abacus” which has one upper row of beads and four lower rows. The Soroban abacus is particularly effective for teaching mathematical calculating skills to young children.
Using an abacus, a child can do all arithmetic calculations up to 10 digits and master the skill of doing it mentally, without relying on modern devices such as calculators.
There are procedures and training methodologies to master abacus use. Research show that when children use both hands to move the beads for small and large arithmetic calculations, the quick communication between hands and brain not only stimulates brain cells promoting speedier and faster calculation ability but also promotes quick, balanced and whole brain development.
Millions and millions of children in the eastern world are now enjoying the benefits of abacus mental math education. 56748 + 632 and you scramble around looking for a calculator, but the very same problem can be solved without any aide of modern day electronic devices such as calculator. Such problems are solved in 5 seconds or even less, by a 6 year old studying abacus mental math for a bit over a year. Such is the power of abacus mental math education.
Today, the same educational materials used in Asian nations are available in the United States, Canada, UK, Europe and South Africa. Today various websites offer not only easy to understand textbooks on abacus math but also math practice worksheets. And this is the kind of practice that engages a child to learn math with a lot of fun. Now you know why Asian children are very good with numbers. And now you know why you see hundreds of Chinese engineers and Indian doctors.

Is your child struggling in math?
We all love to see our children succeed academically, but few of us can afford private tutoring programs to help them achieve their true potential.
You can provide your child with the opportunity to improve math skills in your own home, using techniques that are already helping schoolchildren around the world. You can do this by incorporating easy, enjoyable abacus education into your child’s free time with Learning Mathematics with the Abacus, a set of books developed specifically for teaching youngsters in grades 2, 3 and 4.
Many schools in Asia, where abacus education is widely popular for teaching mental math/arithmetic, introduce the abacus between kindergarten and 4th grade. Studies show that if a child starts learning the abacus before being taught traditional arithmetic, there is minimal conflict and the child will easily work within both systems. If a child starts the program later, having already received traditional foundations, there may be a slightly extended learning period for the child to accept and integrate the abacus method.
With abacus education, children achieve much more than just excellent math skills. Abacus use can build confidence, provide a sense of achievement, promote intuitive thinking, enhance problem-solving capability, stimulate creativity, and improve concentration and mental endurance.
Abacus calculation relies on the manipulation of beads rather than use of traditional arithmetic. It teaches children to visualize numbers and their relationships and placement values.
“Once children understand numbers, they will probably become fond of mathematics,” says Ms. Kimiko Kawano, a researcher at Nippon Medical School, Center for Informatics and Sciences in Japan. She has been studying EEGs of brain waves in subjects doing various mental activities. Her findings show that abacus training develops visualization and memory skills that can help people succeed in other academic areas besides mathematics.
When children use both hands to move the abacus beads to perform arithmetic calculations, there is quick communication between the hands and the brain that stimulates both the right and left hemispheres of the brain. This promotes rapid, balanced whole brain development, which in turn helps your child succeed in other academic areas.
“Abacus students are found to be superior in the accuracy of their memory and the number of digits they are able to memorize when compared with non-abacus learners of the same age. This is because abacus students place numbers on the abacus image in their head as they mentally calculate with the abacus method,” says Ms. Shizuko Amaiwa, Professor at Shinshu University, Faculty of Education, in Japan. She is a psychologist who studies the positive effects of abacus education on overall mental ability.
A popular abacus program available exclusively in the United States through NurtureMinds.com, offers books containing simple step-by-step instructions that make learning the abacus fun for children. This set of books, Learning Mathematics with the Abacus, was developed specifically for teaching youngsters in grades 2, 3 and 4 how to master mental math/arithmetic with the abacus. The site also offers the Japanese Soroban abacus, which is ideal for teaching purposes.
You can find all the materials you will need to help your child master mental math/arithmetic and improve school math grades at the above mentioned website. You can also download free pages from the books and see for yourself how effective they can be for teaching your child valuable mental math skills.

Differences Between Abacus Math And Vedic Math
January 27th, 2008 · No Comments
Vedic Mathematics has no legal definition. Hindu philosophy is based on Veda-s (ancient scriptures written in Sanskrit, some say as old as 5000 B.C.) and mathematics translated from these texts is termed as Vedic Mathematics. These ancient scriptures were rediscovered by Sri Bharati Krsna Tirthaji (1884-1960) and he translated the complex text into simpler understandable mathematics.
The system is based on 16 Vedic sutras or aphorisms, which are actually word-formulae describing natural ways of solving a whole range of mathematical problems. Some examples of sutras are “By one more than the one before”, “All from 9 & the last from 10″, and “Vertically & Crosswise”. These 16 one-line formulae originally written in Sanskrit, which can be easily memorized, enables one to solve long mathematical problems quickly. These formulae describe the way the mind naturally works and are therefore a great help in directing the student to the appropriate method of solution.
With Abacus math, abacus is used as a tool to learn calculations. Beads are moved up and down and various columns to represent the number. When children use both hands to move the abacus beads to perform arithmetic calculations, there is quick communication between the hands and the brain that stimulates both the right and left hemispheres of the brain. This promotes rapid, balanced whole brain development. Abacus math should be started at very early childhood, as young as age 4. Abacus math starts at very basic level by teaching the numbers and then progressing to calculations. Eventually the child retains the memory of bead positions and the relevant notation. Abacus math if started during later ages can create a bit of hindrance.
Vedic math is entirely done in mind. Vedic math also starts at a basic level of numbers and gradually progressing to simple additions, subtractions, multiplications and division. Vedic math goes much more beyond just the basic calculations. With Vedic math one can also solve complex geometrical theorems and algebraic problems. Vedic math can be started at later ages as well without any difficulty.
The key in both techniques is to practice and implement the methods in your day-to-day life. And what could be a better way to practice then using the math worksheets. Today there are various websites you can refer to gain knowledge of either method.

Mastering Time Tables with Fun
January 27th, 2008 · No Comments
According to researchers visual memory is a very crucial aspect of learning. For learning tables with the abacus the children will use both their hands for moving the beads. The synchronizing movement of the hands initiates the cell development in the brain and also utilizing the right part of the brain which is very important to actually master something.
The human brain is divided into two parts the left brain and the right brain. What is used by children most of the times is only the left brain and the right brain which is the actual seat and origin of intelligence is left unutilized. This very important part of the brain integrates whatever information is received and is also responsible for thinking and creative human activities. The learning of time tables through the abacus is one of the many activities that prompts simultaneous activity of the both the parts of the brain.
The use of the abacus is not just a better method for learning time tables over rote memorizing but also the abacus being an attractive tool manages to capture the undivided attention of the child too. It eliminates the phobia attached to tables and makes the processing of numbers a relatively easy activity for them.
Numerical memory and improvement of the spatial arrangement of memory are most enhanced by the use of the Abacus. Apart from that the skill of solving general mathematical problems of the elementary school grade are seen to improve too. The facts stated here are backed by results of tests conducted among children, one group using the Abacus method and the other group without this method. The group using the Abacus method was more efficient naturally as they correlated the calculation with the Abacus image in their minds and were not confused.
So choosing the abacus method for your children will definitely give you the satisfaction of ensuring for them a better future. This will be by making their basics strong right from the beginning. Go ahead get the abacus advantage for your child and recommend it to other people as well so as to pave the way for a sound and confident future for the young generation.

Learning Math With Manipulatives - The Abacus
January 27th, 2008 · No Comments
Representing Numbers With a Dusty Abacus
When I first started using an abacus as a manipulative in math class, I was teaching grade six. In the grade six curriculum, students were supposed to represent whole numbers greater that one million and decimal numbers to thousandths. If you count the number of places from one million down to thousandths, you get ten places. Coincidentally, the abacus had ten rods of ten beads each. I’m sure what I discovered was discovered long ago, and some manufacturers probably even send out better instruction manuals that make note of this, but at the time, it was a completely new discovery.
To make a long story short, I assigned each row a specific place value starting with millions at the top, and thousandths at the bottom. One could use a strip of tape or an indelible marker to label the rows. To represent a number, a student would simply move the number of beads for the value of each place in the number they were given. For example, the number 325,729 was represented by moving three of the hundred thousands beads, two of the ten thousands beads, five of the thousands beads, seven of the hundreds beads, two of the tens beads and nine of the ones beads.
I didn’t have a class set of abaci, so I made up little sketches of an abacus (six or so per page) and students showed representations of numbers using these.
Adding and Subtracting Numbers With a Polished Abacus
Once students are familiar with representing numbers using an abacus, they can move onto adding and subtracting numbers. The idea of adding using an abacus and place value is quite a simple process. Begin by representing the first number. Add the value of each place value in the second and subsequent numbers one at a time beginning with the lowest place value and regroup as necessary.
Consider this simple example, 178 + 255. The student would represent 178 on the abacus to begin. She would then add five to the ones row. Since there aren’t five more beads to add, this first move would also involve regrouping. The student would move the two remaining ones, then regroup by sliding all ten ones back and replacing them with a ten. She would then move three more beads since she already moved two of them for a total of five. Since there was some regrouping, there would now be eight tens. The students needs to add five more, so there would be another regrouping, this time of ten tens to make a hundred. Finally, the student moves two additional hundred beads; this time regrouping isn’t necessary. If everything was done correctly, the student would end up with four hundreds beads, three tens beads and three ones beads.
A variation on addition is to add the second and subsequent numbers from the highest place value to the lowest place value.
Subtracting is much the same as addition, but it involves “removing” beads. The procedure for subtracting is to represent the first number then to subtract the value of each place value in the second and subsequent numbers beginning with the highest place value.
Consider this example, 3.252 - 1.986. The student would first represent 3.252 using the abacus. He would begin by subtracting one one. This is fairly straight forward because there are enough ones available. In the next step, though, the student has to subtract nine tenths from two tenths. He begins by subtracting two of the nine tenths, but he then has to regroup one of the remaining ones into ten tenths. Once he has ten more tenths, he can subtract the remaining seven tenths. He continues by subtracting eight hundredths from five hundredths, and again, he has to regroup, this time, one of the tenths into ten hundredths. The final step also involves regrouping since six thousandths must be subtracted from two thousandths. In the end, the student hopefully ends up with one one, two tenths, six hundredths, and six thousandths (1.266).
Subtraction could also be accomplished by subtracting the lowest place value first, but this sometimes means more manipulations of the beads which means more chance for error.
Conclusion
The use of the abacus takes a little bit of time to master. It is important that the teacher and the students use the correct place value terminology (e.g. “regroup ten hundreds to make one thousand” instead of “turn ten green beads into one blue bead”), so the concepts of place value, addition, and subtraction can be transfered to mental strategies and paper/pencil algorithms. Remember, the best way to dust and polish an abacus is with little fingers!
