Mathematics is a dynamic discipline that prepares students for a world that requires logical thinking and quantitative analysis. Mathematics has always been considered as one of the core subjects in the education system and used in every aspect of life.

YES Mathematics promotes both inquiry and application, helping students to develop problem solving techniques that transcend the discipline and that are useful in the world beyond school. 

Students at YES learn how to represent information, to explore and model situations. Mathematics is content and process; therefore, students should experience both. The content and methods of teaching mathematics at YES reflect the Common Core Standards, developing upon essential conceptual understandings and procedures.

In our vision, school mathematics takes place in a situation where: 

(1) Children learn to enjoy mathematics.
(2) Children learn the importance of mathematics.
(3) Mathematics is a part of children’s life experience.
(4) Children pose and solve meaningful problems.
(5) Children use abstractions to perceive relationships and structure,
(6) Children understand the basic structure of mathematics and
(7) Teachers expect to engage every child in class.

What is the significance of mathematics at YES?

YES mathematics aims to equip all students with the knowledge, understanding and intellectual capabilities to address further courses in mathematics, as well as to prepare those students who will use mathematics in their higher studies, workplaces and everyday life.

It aims to teach how to analyze data, identify patterns, and develop creative solutions to complex problems. These skills are essential in today's fast-paced, data-driven world and are highly valued in many industries, including finance, healthcare, and technology. Theyalso provide an important foundation for the study of sciences, engineering and technology, as well as a variety of applications in other fields.

How is mathematics structured at YES?

The YES mathematics framework encompasses number, algebra, geometry, statistics, probability and so on.
Standard Mathematics aims to give all students a sound knowledge of the basic mathematical principles of formal problem solving as well as investigating the underlying principles of mathematics includes heuristics, estimation and approximation, optimization the use of patterns, visualization, representation, reasoning and proof. We aim to engage every student with a sense of success, while allowing them to develop the skills needed to meet the objectives of YES mathematics. 
Extended Mathematics, supplements the standard mathematics framework. With this additional topics and skills, providing greater breadth and depth. This Provides the foundation for students who wish to pursue further studies in mathematics and Offers conceptual challenges to the emerging mathematician.
We use simple yet effective instructional methodologies: 

1. Make conceptual understanding a priority
Students need a deep understanding of mathematical concepts themselves. Using visual strategies is important -making a concept visual allows students to see how an abstract concept translates to a physical scenario. Using illustrated problems or hands-on activities, and encourage students to use visual methods of their own (e.g. drawing, making Models) when solving problems.

2. Use of strategic questioning
Strategic questions can help turn a regular ‘chalk and talk’ lesson into a deep learning experience.
Instead of congratulating a student when they get an answer correct and moving on, it's better to ask them to communicate their approach. This achieves two things:
The student is encouraged to reflect on their own thought process in detail. Instead of just doing the math automatically, they’ll understand exactly the steps they took – and begin to see how these might be adapted to future, more challenging problems.
Other students get the opportunity to see how they could have solved the problem, even if they struggled to do so originally.
And questions like “Where could you use this…” or “where would you see this used in the real world?” drive home the relevance of the learning. Instead of procedural knowledge alone, students will also come away with an understanding of how to apply that knowledge.

3. Mental Math strategies and Break down the problem
Mental math
Is a group of skills that allow students to do math “in their head” without using pencil and paper or a calculator. Mental math is useful for students both in school and in everyday life. It will help kids understand math concepts better and also get to the answer faster.

Break down Method 
Instead of jumping to a final solution, students will have much more success if they break a bigger problem into a series of smaller ones, and then move through these systematically and reach a final solution.

Our vision of excellent mathematical education is based on the twin premises that all students can learn mathematics and that all students need to learn mathematics. It is therefore imperative that we offer mathematics education of the very highest quality to all children.

At YES, we use the Rubik’s cube as a teaching aid to get children interested in mathematics. Solving the Rubik’s cube is a great way to learn algorithms. In some classes, we also link it with programming classes and calculate the number of patterns in the Rubik’s cube. We believe that the Rubik’s cube is a tool that kills two birds with one stone. It is fun to play with while also providing math training.

Beaver challenge study cards – Using the “Beaver challenge study cards” provided by the CTC Foundation for the future, we are also developing exploratory classes that foster logical thinking skills while having fun.

In Japan, there is an arithmetic calculation system called “99” that is unique in the world and at Yes students study 99 just as they do in Japanese schools. However, we do not necessarily force students to memorize any step first, or by reversing Shi-san-juroku so that they do not have to memorize Shi-San-juroku in addition students who prefer to memorize whole terms are asked to memorize them as they are. “Math is free” is the motto of the YES math department.
