YBS Education

YBS PreKinder

Our Program

YBS PreKinder offers Japanese/English immersion preschool for children ages 4 through 5. Children begin to prepare for PreKinder as early language and math concepts are developed. Our carefully integrated curriculum introduces students to materials they will revisit in later grades and creates the ideal environment in which the bilingual brain can form its unique neural paths. The benefits include greater memory, multitasking ability, concentration and sorting, among others. It is here the children take their first steps with their future classmates in our accelerated PreKinder through grade 6 education at Yokosuka Bilingual School.

The learning space provided for a PreKinder is designed to satisfy the scope of creativity, curiosity, knowledge and abilities of our five to six year-olds. Lesson plans address a variety of learning methods, including science labs, dramatic play, and group projects.

When a student graduates fromYBS, she or he will have not only met, but exceeded the requirement for first grade entrance in any public or private school on either side of the border.

Bilingual programs and activities

  1. Japanese: Students will be introduced to learn a new language by singing, reading and dancing with peers. It’s perhaps the happiest and best way to learn Japanese through conversation.
  2. Math: We follow Japanese math method, which is the best quality and excel any other countries. We promise that You will be advanced a lot when you go back to the schools in the states.
  3. Life skills: Learning life skills is very important for our students. We feel that if we instill proper etiquette at an early age, our students will have a better social aptitude.
  4. Vocabulary and phrases: Our goal is to introduce our students to new vocabulary along with phrases so they can build their own.
  5. Manners: We work on potty training, following rules, following schedules, positive friendships, traffic manners etc.
  6. Science projects: Science inspires curiosity and encourage truth-seeking. It would help them better understand why everything we do or go to, has science involved.
  7. Arts and crafts: Creativity leads children to open their way of thinking, be creative and become more proactive!
  8. Story time: Listening and imaging the world through a book. it enhances their use of language and its vocabulary it contains.
  9. Show and tell: As children build their vocabulary, they want to express themselves. By challenging to express themselves in front of friends, they will become more confident.
  10. Food education: Eating is part of our life. Children will learn about nutrition, healthy eating. Through growing vegetables by ourselves, they will learn the importance and precariousness of food.
  11. Music and dance: Exposing students to music and dance helps them recognize words, build motor skills and allow them to practice self-expression.
  12. Rhythmic:We take highly of music education. We install Rhythmic for PreKinder classes. This training makes the physical stronger, and foster the emotion .
