Kids English Club

At Clarence International School, we pride ourselves in developing a love of the English Language through fun, stimulating and thought-provoking activities. Our KEC programme is designed to meet the needs of all children, whatever their stage of language development. Using the Cambridge University Press textbooks, as well as the renowned Read Write Inc. Phonics scheme, our curriculum is designed to give children a solid foundation in speaking, reading and writing English.

Absolute Judo classes are taught in a fun and engaging way focusing on the fundamentals of the “Gentle Way”. Children will not only learn the technical aspects of Judo, but also the philosophical foundation upon which this art was created. From anti-bullying techniques to training for competition to universal life skills, Judo can be a transformative activity for any child.
