Kumon Maths follows the Kumon Method, a series of graded math worksheets that students work through independently, to master the basic skills of mathematics.

There are more than twenty graded levels within the Kumon Maths program stretching from toddler to college levels and students work through them systematically, repeating and rerepeating each set as necessary, until they have mastered the skill being taught in that series of worksheets.

Each student is tested at the start of their program, and begins at a level that is easy for them; what Kumon calls a "comfortable starting point." This helps to increase the students confidence and motivation whist reinforcing basic skills.

One of the key features of the Kumon method is that no calculators are used. As a result students become fast and accurate at basic arithmetic as well as more advanced mathematics

Kumon does not offer children individual tutoring. The majority of the math worksheets are done at home and marked by parents. Instead new concepts are introduced at the start of a new worksheet booklet, providing a simple example, and the student then begins to attempt questions immediately. The work is graded and introduced in such small steps that there appears to be a natural progression. This avoids students becoming discouraged and losing confidence.

Once or twice a week the student attends a Kumon centre where a supervisor checks the completed work and assigns new worksheets.They also administer any assessment tests that may be required.

Students have to gain complete mastery of a subject before they are allowed to move on to the next level. This is judged not only by the accuracy of their work but by the time in which it is completed.

One of the great advantages of Kumon is that it allows students to progress at their own pace. Students are not required to study at their grade level, rather, they progress to the level at which they are comfortable. Often students may be studying 2-3 years above their school grade level.

Many students of Kumon maths report improving their class positions as well as greatly increasing their confidence in mathematics. .

Whilst there is no question that for many children Kumon works at improving their maths grades and proficiency, and increasing their confidence in their own abilities, there are also disadvantages of the system.

One of these is that many students complain that the worksheets are boring. Often students are required to repeat worksheets as many as 6 or 8 times. For some students this is very discouraging and it is hard to maintain their motivation for the program.

Another disadvantage is the time involved. Kumon study usually requires around 20 minutes of focused study each day. For some busy families this proves a large stumbling block to following the program. Whilst parents aren't required to actively teach their children many centres ask that they mark and correct the workbooks and also that students times to complete worksheets are recorded.

Although Kumon covers key elements of mathematics at the primary school age it does not attempt to cover the whole curriculum until high school age. This means that for junior school pupils only 15-20% of the mathematics required is covered. Kumon focuses on the key skills of addition, subtraction, multiplication and division in the early stages.

Another disadvantage is cost. In some countries the program costs as much as $100 per subject a month. For many families this can be prohibitively expensive.

Although the Kumon program is fairly unique there are several websites that offer online printable mathematics worksheets. Many of these websites offer them by school year, and by concepts to be learnt. These can provide an alternative for a dedicated parent.

Kumon themselves also publish a huge range of Kumon workbooks for children to complete at home without actually following the Kumon program. Whilst these are not as comprehensive as the kumon program itself they are substantially cheaper and are a good substitute for someone looking for a cost effective alternative.
