# ELEMENTARY MATHEMATICS WITH A 100-BEAD ABACUS

The best tools to teach first or second-grade student mathematics is with a 100-bead abacus. The 100-bead abacus is simple in its construction. It has ten wired with ten beads strung together on each wire. The simple abacus is not as sophisticated as the Chinese or the Japanese abacus. The simple abacus is used to help teach the basics of counting. To make it more simple and easy to understand, each of the beads represents a ‘1’.

There is no need to confuse a 1st grader about the sophisticated uses of the abacus. Instead of treating it as a simple one is the best way forward. Teaching elementary school kids about the place value of double-digit numbers have to be a straightforward process. Complicating the abacus will not reinforce the idea behind the place values.

## Ways to Teach Kids Mathematics Using the Abacus

The simple abacus teaches kids about the unit’s place and the ten’s place, which is enough for their standard. There are simple games that can be used to teach kids about the abacus. The best kind of abacus are ones that have alternating colors so that children will be able to recognize the 6, 7 and 8th place on the beads without having to count manually.

## Number Games

Simple games are great ways to introduce the abacus. Games such as ‘say and show’ are great for this purpose. The teacher can say a particular number and the child can show the number on the abacus. The roles can be reversed to make it fun. A reward will be a good goal for the greatest number of correct answers.

When teaching addition, you can select six beads and eight beads on two different wires. You can then demonstrate how there are five beads on both the cables and there are some left over.  A simple way to understand and master addition.

## Subtraction

Show the child how subtractions of two numbers would work. Use multiples of 5 when you teach them the subtraction. For example, give them 10-5 and use the same pattern of names for the different sums. At a point, the child will understand that there is a pattern to the subtraction and will know how it works.
