At what age are Kumon Arithmetic 2A materials?
Kumon Math 2A is the equivalent level of 5 years old.
In Kumon, the A materials for any subject are at the level equivalent to 6 years old. 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... I think it is generally correct to think of Kumon Math 2A as being for 5 year olds, 4A and 5A as being for 4 year olds, 6A and below as being for 3 year olds, and so on.
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 TATSU-3, students learn TATSU-4 through TATSU-10 in order to develop their basic arithmetic skills, and then develop the skills to move on to the A materials of addition and subtraction.
Addition was introduced for the first time in 3A, and 2A is an extension of this material. The number of addition numbers increases to 10.
Let's look at the material in more detail. Arithmetic 2A consists of 200 printouts, and the contents are largely divided as follows.
| 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 addition numbers increase step by step and that the learning progresses quite carefully.
What are the key points of Kumon Arithmetic 2A?
The key to success in Kumon Math 2A is to earn the number of times you do addition anyway.
Kumon addition is more like memorization than understanding.
If you imagine an addition class at school, the class is taught by explaining the meaning. In many cases, Kumon classes are taught by showing concrete objects and counting on one's fingers to help students understand the concept of addition.
However, in Kumon's math classes, concrete objects are not shown when teaching addition, at least not in the printed materials. There may be some supplementary instruction in counting with fingers, but basically, the goal is for students to be able to look at an equation and get the answer.
This is a similar concept to when studying ninety-nine. In Japan, the final goal is to master single-digit multiplication by reciting up to 99. In India, the goal is to memorize up to 1919. In India, it is said that students memorize up to 1919, but here too, the basis is memorization. Even if you understand the meaning of multiplication, if you do not memorize it, the calculation will be very time-consuming.
In Kumon math, addition is taught with the same concept. The goal is to memorize the answers by repeating addition of the same numbers over and over again.
For memorization, frequency is more important than proper explanation.
So what is important for memorization? Without a doubt, it is the number of repetitions that is important.
Of course, once the amount of memorization exceeds a certain level, trying to memorize in the dark will not be effective. This is because trying to memorize 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 if it is a single digit, the pattern does not even reach 100. Moreover, the answers are regular, and even if you forget what you have memorized, you can easily derive the answer by counting with your fingers. Simple memorization is a very effective learning method for such a subject.
And there is no better way to do simple memorization than through repetition. The focus should 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 is to earn the number of times to solve addition.
First, make sure they understand that "3+1=" reads "Three add up to one." The first step is to make them understand that "3+1=" is the same as "What is the number one that adds three? When they are solving Kumon printouts, read the equation to them from time to time to help them understand how to read the equation.
Once they understand 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 may also be effective. However, once they have a certain level of understanding, you can expect them to solve addition puzzles on their own outside of Kumon.
