At what age are Kumon Maths 2A teaching materials?

Kumon Maths 2A is the equivalent level of 5 years old.

In all Kumon subjects, the A materials are at the equivalent level of 6. Under 2 years of age, children study in a separate material called 'Baby Kumon', so it is generally safe to assume that 2A and 3A are for 5-year-olds, 4A and 5A are for 4-year-olds and 6A and below are for 3-year-olds...

What kind of materials are Kumon Math 2A?

The aims of the Kumon Math 2A materials are as follows

Based on the skills acquired in the 3A materials up to tsukasu 3, the students study tsukasu 4 to tsukasu 10 in order to develop their basic mental arithmetic skills for addition and subtraction, and to develop the skills to move on to the A materials.

Addition was introduced for the first time in 3A, and 2A is an extension of this. The number of additions increases to 10.

Let's look at the material in more detail. Maths 2A consists of 200 printouts, which are largely divided into the following sections.

| Material number | Content | | | --- | --- | | 1-10 | Review of 3A | | | 11-30 | x+4 | | | 31-50 | x+5 | | | 51-70 | x+1 to x+5 | | 71-90 | x+6 | | | 91-110 | x+7 | | 111-130 | x+1 to x+7 | 131-150 | x+8 | | 131 -160 | x+9 | | 161-170 | x+9,x+10 | | 171-200 | x+1 to x+10

All single-digit additions are handled here. You will also see that the increase in the number of digits to be added is done step by step, and that the learning progresses quite carefully.

What are the key points of the Kumon Maths 2A strategy?

The key to Kumon Math 2A is to earn the number of times you do the addition anyway.

Kumon addition is more like memorisation than understanding.

If you imagine an addition class at school, the class is taught by explaining the meaning. In many cases, classes are taught by showing concrete objects and counting on fingers to help students understand the concept of addition.

However, in Kumon maths, concrete objects are not shown when teaching addition, at least not in print. There may be some supplementary instruction on counting with fingers, but basically the goal is to enable students to look at the equation and get the answer.

This is a similar concept to when studying ninety-nine. In Japan, the final step is to master single-digit multiplication by reciting up to 99, although there is a part of the ninety-nine where the meaning is taught. In India, it is said that up to 1919 is learnt, but here too the basis is memorisation. Even if you understand the meaning of multiplication, if you don't memorise it, it is very time-consuming to calculate.

In Kumon maths, addition is taught using the same concept. The goal is to memorise the answers by repeating addition of the same numbers over and over again.

Frequency is more important for memorisation than proper explanation.

So what is important for memorisation? This is definitely going to be the number of times you repeat the answer.

Of course, if the amount of memorisation exceeds a certain level, trying to memorise in the dark will not be effective. This is because trying to memorise detailed lines and settings without reading the Harry Potter stories is usually not very effective.

However, addition does not have a large number of patterns, and with single digits, the patterns do not even reach 100. Moreover, the answers are regular and even if you forget what you have memorised, you can easily derive the answer by counting with your fingers. For these subjects, simple memorisation is a very effective learning method.

And there is no better way to do simple memorisation than through repetition. The focus will be on how many times you can simply do it.

Let's make the number of times everywhere.

Therefore, the key to success in Arithmetic 2A will be to earn the number of times you have to solve addition.

First, make sure they understand that "3+1=" reads "What is three plus one?" This is the first step in preparing them to understand that "3+1=" is the reading "What is three plus one? Sometimes when they are solving Kumon printouts, you can read the equation to them to help them understand how to read the equation.

Once they know how to read, you can ask them to add in everyday life. There are many situations in daily life where you will be asked to count, so if you give them addition at every opportunity, they will remember addition as an episodic memory.

Once they have a certain level of understanding, posters can also be useful. If you force your child to show formulas while they still don't understand them, they may not be interested, but once they understand them to a certain extent, you can expect them to solve addition on their own outside of Kumon.
