# Discover Addition and Subtraction using Spike Abacus

### July 9, 2020

**Reading Time: 2 minutes**

*Addition and subtraction are basic concepts that are taught to children from a very young age. These are two concepts that we use throughout our lives, so it is important to make children understand the underlying concepts from an early age. In most cases, these concepts are taught using mechanical processes.*

This method ensures that children learn * how *to perform calculations but they don’t usually understand

*the algorithm really works?*

**why**Even if they are curious to know, their doubts are probably dismissed when they ask questions in their classes.

In order to explain *why* it is best to make use of learning aids. The spike abacus is one such recommended tool to explore and explain the concepts of addition and subtraction. Let’s learn more about it.

**Let us Understand How the Spike Abacus Really Helps**

1. **Addition using an abacus**

We can for example represent 12 as 2 disks in the ones’ place and 1 disk in the tens’ place. Similarly, 25 is 5 disks in the ones’ place and 2 disks in the tens’ place. We know that addition is a combination of numbers. On combining the two numbers, we get 7 disks in the ones’ place and 3 disks in the tens’ place and this can be read as 37.

2. **Subtraction using abacus:**

Let’s consider subtracting 12 from 25 as an example. In this case, we take away the second number from the first, which is the basic definition of subtraction. So we take away 2 discs from 5 and are left with 3 discs. Then we take away 1 disc from 2 to get 1 disc. This number is 13.

The spike abacus is a part of Cuemath’s Mathbox along with many other learning aids used for learning various concepts. Cuemath suggests the use of such learning aids for the following reasons:

**Students get hands-on experience in calculation**

The spike abacus is an adjustable manipulative that students can experiment with. Once they learn to calculate with this, the process of adding and subtracting becomes much simpler.

**It promotes the understanding of the why behind the what**

With the spike abacus, children don’t just learn what ones, tens, and hundreds are but also visually experience what they are. The concepts of ** carryover** in addition and

**in subtraction become clearer when students see the discs being moved from one rod to the other.**

*replacement***It is more attractive and interesting to work with**

What makes the abacus popular among Cuemath students is the fact that it is friendly and fun to work with. Unlike textbooks, the spike abacus is more welcoming and easy to understand.

Expose your children to the ** why** behind a process at a young age so that they understand the basics from the beginning. It becomes difficult to unlearn a process that has already been ingrained in them since their childhood.
