![]() ![]() A student of any math level can use it, which makes it great for all ages. It allows the student to see the numbers and how they relate to each other and have confidence to try and solve them. Similar to math manipulatives with younger children, the abacus builds independence to tackle math problems.This method involves imagining counting the beads, instead of physically moving them, which also strengthens imagination. In addition to the benefits of physically moving of the beads, there is a method to using the abacus that is strictly using the mind.It teaches the brain to associate abstract thought with a physical object, building spacial reasoning and imagination. This in turn, frees up the brain to complete more complex calculations. Instead of having to memorize facts and tax the short-term memory, it allows for solving without having to memorize these strategies. The brain can only store so much in short term-memory. It lightens the load on our short-term memory.There are so benefits of using the abacus to assist in math calculations. Many kids have success learning the traditional version as early as 5 or 6 years old. We have started all the kids using the simple school abacus early on, and only transition to the Sorobon or Suanpan as they are able to count to 100 and easily manipulate the beads. Another name for the base 10 numbering system is the decimal system.īecause the layout of the simple school abacus is so different than the Soroban or the Suanpan, I like to have both a simple school abacus and a Soroban or Suanpan on hand. Some people find the Soroban to be more simple and easier as it uses the familiar base 10 numbering system. The Soroban uses the base 10 numbering system, while the Suanpan used the base 18 numbering system. Another name for the Suanpan is the 5+2 abacus. On the Suanpan, you count the five lower beads before you can exchange it for one upper bead. Another name for the Soroban is the 4+1 abacus. After you count the four lower beads, you can exchange it for one upper bead. ![]() The Soroban has four beads in the lower column and one bead in the upper column. It is slightly different from the Chinese Suanpan abacus. What’s the difference between the Soroban and Suanpan? The simple school version often times comes in colorful beads, making it appealing to young children and easy to distinguish between the place values. It helps in teaching place value, adding and subtracting as well as division and multiplication. This format can be instrumental in teaching young children how to count and how to visualize groups of ten. In this version, the lowest row represents the ones place, the row above it, represents the tens, continuing upwards. The simple school abacus stands upright and has ten rows of ten beads. The upper deck beads are each valued at five times the amount of one lower beads.Įach column represent a place value, the far right column representing the ones place, the next column representing the tens place, the next column to the left representing the hundreds place and onward. It is prepared for use, or zeroed out, by laying it flat on a table and pushing all the upper beads up and the lower beads down. The top portion is called the upper deck and the bottom portion is called the lower deck. ![]() When using the abacus, you use either your index or thumb to manipulate the beads. That’s a lot of functions for this small, simple, wooden tool! It can be used to perform addition, subtraction, division and multiplication as well as extract square roots and cubic roots. Each culture has taken on a slightly different version of the tool. The abacus goes by many names including Suanpan, Soroban, and Shoty. It was first discovered in Ancient Mesopotamia, but made it’s way from the Middle East to Japan, China, Russia and around the world. The abacus is said to be the world’s first calculator. I always said that I was more of a words person, but I believe that numbers could have come easier for me, had I used an abacus to help strengthen my number sense. Numbers have never come really easy for me. It honestly wasn’t until I was an adult that I learned how to properly use the abacus and when I found out, I wished I had learned it’s use much earlier on in life. I couldn’t figure out what the significance of seven beads in each row meant. ![]() I’d count each bead under my finger and wonder what the beam in the middle was for. I knew the abacus was a mathematical tool, but I had no idea what each bead meant. Replicating the sound, I’d tilt it down to hear the beads crash again as they hit the bottom. I’d tilt the abacus down to hear all the beads crashing to the top. I vividly remember playing with our old black, wooden abacus in our basement as a child. How to Use an Abacus and Why Your Child Needs Oneĭid you grow up learning how to use an abacus? Although we had one in our home, in my mind, it was nothing more than a useless wooden toy. ![]()
