## At what age are Kumon Maths D materials?

Kumon Maths D is the equivalent level of 10 years old.

From the A materials onwards, the alphabet is designed in such a way that when the alphabet advances by one letter, the grade level also advances by one letter. Although some parts of the arithmetic do not deal with shape problems and there is some divergence between the grade and the alphabet, basically the alphabet and the grade can be considered to correspond to each other.

In Japan, there is also an award system whereby if your child is three grades ahead of your child's grade as of 31 March, he or she will receive a trophy. If they have completed the D materials in the first grade of primary school, they are eligible for the award.

If your child has started Kumon learning from an early age, you can consider that they are on track to learn ahead of their class if they have reached this point at the age of 7 or 8 years old.

## What kind of Kumon Math D materials are they?

The aims of the Kumon Math D materials are as follows

To further develop the students' four arithmetic skills up to the C materials, and to develop the calculation skills necessary for learning two-digit division. In addition, they acquire the ability to divide by two, become familiar with the number of fractions and move on to the Kumon E materials.

As a step towards fractions, the focus is on two-digit division.

Let's look at the teaching materials in more detail. Arithmetic C consists of 200 printouts, which are broadly divided into the following sections.

| Material number | Content | | --- | --- | | 1-10 | Review up to C | | 11-40 | 2 x 2 digits | | | 41-50 | 3 x 2 digits | | | 51-60 | Addition and subtraction | | 61-80 | Multiplication and division | | 81-130 | Division with 2 digits | | 131-150 | Division with a quotient greater than 2 digits | | 151-160 | Fractions | 161-200 | Approximate divisors | 151-160

The number of digits in multiplication and division performed in the C materials will increase; having mastered two-digit calculations, you will be able to move on to mastering fractions in the fullness of time.

## What are the key points of Kumon Math D?

The key point of Kumon Math D is how to continue the repetition of basic practice, which is not fun.

### The content of the D materials is a combination of the content of previous studies

It can be said that almost all of the calculations that appear in the D materials are made up of combinations of existing techniques.

For example, two-digit by two-digit multiplication is made up of two-digit by one-digit multiplication and addition if you break down the content of the written work. Fractions are indeed a new concept, but most of the actual calculations performed, even with divisors, are one-digit divisors.

Unlike when addition and multiplication first appeared, this material is designed to progress by learning and combining previous skills at a high level.

### Teaching materials that involve constant repetitive practice of the basics.

Mastering basic calculations at a high level is a Kumon speciality. By repeating the calculations thoroughly, students can do them much faster than usual. Children who have completed this area of content at school with Kumon may stand out a little in calculation situations.

It is worth noting, however, that the speed of their calculations is not brought about by special techniques. The quality of their calculations is enhanced by thorough repetition and simply by solving a large number of calculation problems.

Steady repetitive practice is naturally not fun. Kumon has no tricks to entertain children. From your child's subjective point of view, it is not difficult to imagine that it can be a painful material, with endless solving of heavy calculations.

### Let's see it as an opportunity to develop long-term study habits.

The point of Kumon Math D is to somehow continue to support your child during a tough phase.

The way you support your child depends on his or her personality. Some children are encouraged to get stronger, while others do their best by being scolded when they are slacking off. Whatever method you use, you want to communicate with your child in a way that encourages them to work hard when times are tough.

It is important to bear in mind that this is a material that could be worked on over a period of six months or a year. The approach of fishing with short-term rewards is less likely to work over such a long period of time.

It is effective to work with your child to develop the desire to go to the desk with the intention of building study habits that will last for years to come,
