![]() The left or logical brain and the right or creative brain. The human brain can be considered to be divided into two parts or hemispheres. About thirty years back it was discovered that this simple calculating instrument can be an important brain development tool for kids between 6 to 14 years of age. Kids who have done abacus courses up to certain levels are able to visualize the abacus instrument and do long calculations mentally with astonishing speed.Ībacus is an ancient calculating instrument that was primarily invented for doing calculations. Mental math is the technique of doing calculations mentally without using any pen paper or calculator. To understand abacus mental math and its benefits, we have to first know what Abacus and mental math is. There are certain formulas that have to be implemented for doing calculations like addition, subtraction, multiplication, and division.Īlthough invented with the objective of doing calculations, the abacus since the last three decades is widely used as a math improvement and complete brain development tool for kids.ģWhat is Abacus Mental Math and how it will help my child? Every bead has a certain value and calculations are done by moving the beads on rods. Thus a child doing abacus not only shows improvement in mathematics but also excellence in all the subjects.Ībacus is a frame having rods and beads. On activation of both the parts, a child gets excellent calculating skills and number sense along with improved concentration, photographic memory, recall, and listening ability. The left hemisphere is responsible for logic, numbers, and calculation. ![]() The right hemisphere is responsible for creativity, concentration, recall, and photographic memory. Predominantly only one part or hemisphere of the human brain is more active which in 90% of cases is the left one. The abacus primarily is a complete brain development program that simultaneously activates both left and right hemispheres of a child’s brain. It is imperative to understand that math is only a tool in abacus learning and math improvement is only one of the many benefits of this wonderful program. This lead to the discovery of an instrument that used beads for doing calculations and thus came into existence the tool Abacus. This method had its limitations and was not usable for higher calculations. In ancient times when calculators were not there, people used fingers for counting.

For example, you might say 5,342, and students would have to show 5 sky blue beads, 3 blue beads, 4 lavender beads, and 2 dark purple beads. Represent large numbers on the abacus, using the place values mentioned above.Represent addition problems on the abacus.For example, 3 x 3 would be shown as 3 groups of 3 beads on the abacus, each group shown with a different color of beads. Represent multiplication problems as repeated addition.Some activities you might try with the abacus include: Alternatively, simply have students represent each addend with a different color. Students can represent numbers using the different place values and then perform operations. For example, the dark purple beads represent the one’s place, lavender the 10s place, the blue represents the hundreds place, sky blue represents the thousands place, etc. Students can represent larger numbers by assigning each rod a place value. To use the online abacus, simply drag the beads across the rods from left to right or right to left. As they grow in their abilities, students can use the virtual abacus to represent addition, multiplication, or subtraction problems. ![]() In the early grades, students can simply use the abacus to represent quantities and numbers, building number sense. This online abacus tool allows students to model all sorts of operations. Used since ancient times, the abacus is making a comeback in education.
